15kV ESD-Protected, 1A, 16Mbps, Dual/Quad Low-Voltage Level Translators in UCSP
General Description
The MAX3372E-MAX3379E and MAX3390E-MAX3393E 15kV ESD-protected level translators provide the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a high-voltage logic signal on the VCC side of the device, and vice-versa. The MAX3374E/MAX3375E/ MAX3376E/MAX3379E and MAX3390E-MAX3393E unidirectional level translators level shift data in one direction (VL VCC or VCC VL) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gatebased design (Figure 2) to allow data translation in either direction (V L V CC ) on any single data line. The MAX3372E-MAX3379E and MAX3390E-MAX3393E accept VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, making them ideal for data transfer between lowvoltage ASICs/PLDs and higher voltage systems. All devices in the MAX3372E-MAX3379E, MAX3390E- MAX3393E family feature a three-state output mode that reduces supply current to less than 1A, thermal shortcircuit protection, and 15kV ESD protection on the VCC side for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a guaranteed data rate of 230kbps. Slew-rate limiting reduces EMI emissions in all 230kbps devices. The MAX3373E-MAX3376E/MAX3378E/MAX3379E and MAX3390E-MAX3393E operate at a guaranteed data rate of 8Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. (See Timing Characteristics.) The MAX3372E-MAX3376E are dual level shifters available in 3 x 3 UCSPTM and 8-pin SOT23-8 packages. The MAX3377E/MAX3378E/MAX3379E and MAX3390E-MAX3393E are quad level shifters available in 3 x 4 UCSP and 14-pin TSSOP packages.

15kV ESD-Protected, 1A, 16Mbps, Dual/Quad Low-Voltage Level Translators in UCSP MAX3372E-MAX3379E/MAX3390E-MAX3393E
Detailed Description
The MAX3372E-MAX3379E and MAX3390E-MAX3393E ESD-protected level translators provide the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a highvoltage logic signal on the VCC side of the device, and vice-versa. The MAX3374E/MAX3375E/MAX3376E/ MAX3379E and MAX3390E-MAX3393E unidirectional level translators level shift data in one direction (VL V CC or V CC V L ) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gatebased design (see Figure 2) to allow data translation in either direction (VL VCC) on any single data line. The MAX3372E-MAX3379E and MAX3390E-MAX3393E accept VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, making them ideal for data transfer between lowvoltage ASICs/PLDs and higher voltage systems.
VL VCC
All devices in the MAX3372E-MAX3379E, MAX3390E- MAX3393E family feature a three-state output mode that reduces supply current to less than 1A, thermal shortcircuit protection, and 15kV ESD protection on the VCC side for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a guaranteed data rate of 230kbps. Slew-rate limiting reduces EMI emissions in all 230kbps devices. The MAX3373E-MAX3376E/MAX3378E/MAX3379E and MAX3390E-MAX3393E operate at a guaranteed data rate of 8Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. (See Timing Characteristics.) For proper operation ensure that +1.65V VCC +5.5V, +1.2V VL +5.5V, and VL (VCC + 0.3V). During power-up sequencing, VL (VCC + 0.3V) will not damage the device. During power-supply sequencing, when VCC is floating and VL is powering up, a current may be sourced, yet the device will not latch up. The speed-up

circuitry limits the maximum data rate for devices in the MAX3372E-MAX3379E, MAX3390E-MAX3393E family to 16Mbps. The maximum data rate also depends heavily on the load capacitance (see Typical Operating Characteristics), output impedance of the driver, and the operational voltage range (see Timing Characteristics). put mode. Connect THREE-STATE to VL (logic high) for normal operation. Activating the three-state output mode disconnects the internal 10k pullup resistors on the I/O VCC and I/O VL lines. This forces the I/O lines to a highimpedance state, and decreases the supply current to less than 1A. The high-impedance I/O lines in threestate output mode allow for use in a multidrop network. When in three-state output mode, do not allow the voltage at I/O VL_ to exceed (VL + 0.3V), or the voltage at I/O VCC_ to exceed (VCC + 0.3V).

Speed-Up Circuitry
The MAX3373E-MAX3376E/MAX3378E/MAX3379E and MAX3390E-MAX3393E feature a one-shot generator that decreases the rise time of the output. When triggered, MOSFETs PU1 and PU2 turn on for a short time to pull up I/O VL_ and I/O VCC_ to their respective supplies (see Figure 2b). This greatly reduces the rise time and propagation delay for the low-to-high transition. The scope photo of Rail-to-Rail Driving for 8Mbps Operation in the Typical Operating Characteristics shows the speed-up circuitry in operation.
Thermal Short-Circuit Protection
Thermal overload detection protects the MAX3372E- MAX3379E and MAX3390E-MAX3393E from short-circuit fault conditions. In the event of a short-circuit fault, when the junction temperature (TJ) reaches +152C, a thermal sensor signals the three-state output mode logic to force the device into three-state output mode. When TJ has cooled to +142C, normal operation resumes.

15kV ESD Protection
As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The I/O VCC lines have extra protection against static electricity. Maxim's engineers have developed state-ofthe-art structures to protect these pins against ESD of 15kV without damage. The ESD structures withstand high ESD in all states: normal operation, three-state output mode, and powered down. After an ESD event, Maxim's E versions keep working without latchup, whereas competing products can latch and must be powered down to remove latchup. ESD protection can be tested in various ways. The I/O VCC lines of this product family are characterized for protection to the following limits: 1) 15kV using the Human Body Model 2) 8kV using the Contact Discharge method specified in IEC 1000-4-2 3) 10kV using IEC 1000-4-2's Air-Gap Discharge method ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test setup, test methodology, and test results. Human Body Model Figure 3a shows the Human Body Model and Figure 3b shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device through a 1.5k resistor. IEC 1000-4-2 The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to integrated circuits. The MAX3372E- MAX3379E and MAX3390E-MAX3393E help to design equipment that meets Level 3 of IEC 1000-4-2, without the need for additional ESD-protection components. The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD withstand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 4a shows the IEC 1000-4-2 model, and Figure 4b shows the current waveform for the 8kV, IEC 1000-4-2, Level 4, ESD contact-discharge test. The air-gap test involves approaching the device with a charged probe. The contact-discharge method connects the probe to the device before the probe is energized. Machine Model The Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protection during manufacturing, not just inputs and outputs. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.

Applications Information
Power-Supply Decoupling
To reduce ripple and the chance of transmitting incorrect data, bypass VL and VCC to ground with a 0.1F capacitor. See Typical Operating Circuit. To ensure full 15kV ESD protection, bypass VCC to ground with a 1F capacitor. Place all capacitors as close to the power-supply inputs as possible.
ASIC and an I2C device. A typical application involves interfacing a low-voltage microprocessor to a 3V or 5V D/A converter, such as the MAX517.
Push-Pull vs. Open-Drain Driving
All devices in the MAX3372E-MAX3379E and MAX3390E-MAX3393E family may be driven in a pushpull configuration. The MAX3373E-MAX3376E/ MAX3378E/MAX3379E and MAX3390E-MAX3393E include internal 10k resistors that pull up I/O VL_ and I/O VCC_ to their respective power supplies, allowing operation of the I/O lines with open-drain devices. See Timing Characteristics for maximum data rates when using open-drain drivers.
