Low-Voltage, Dual-Supply, SPDT Analog Switch with Enable
General Description
The MAX4564 is a low-voltage, dual-supply, singlepole/double-throw (SPDT) analog switch designed to operate from dual 1.8V to 6V or single +1.8V to +12V supplies. The low on-resistance (RON = 40 at 5V) and low power consumption (5W) make this part ideal for audio, video, and battery-powered applications. This switch offers low leakage currents (1nA max) and fast switching speeds (tON = 60ns and tOFF = 40ns at 5V, max). The MAX4564 is a second source to the Toshiba TC7W53F with lower RON and lower leakage specs. It is available in 8-pin SOT23 and MAX packages.

Note 1: Signals on NO, NC, COM, IN, or EN exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Note 3: Note 4: Note 5:
The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column. SOT-packaged products are 100% tested at +25C and guaranteed by design at the full-rated temperature. RON = RON(MAX) - RON(MIN). Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 6: Guaranteed by design. Note 7: Off-Isolation = 20log10 (VCOM / VNO), VNO = input to off switch.

Detailed Description
The MAX4564 is a dual-supply SPDT CMOS analog switch. The MAX4564 has break-before-make switching. The CMOS switch construction provides Rail-toRail (R) signal handling while consuming virtually no power. Each of the two switches is independently controlled by a TTL/CMOS-level-compatible digital input.

Applications Information
Overvoltage Protection
Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always sequence V+ on first, then V-, followed by the logic inputs NO, NC, or COM. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with supply pins. Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the device's low switch resistance and low leakage characteristics.
