0.7, Low-Voltage, Quad 2:1 Analog Multiplexers
General Description
The MAX4780/MAX4784 are low on-resistance, lowvoltage, quad 2:1 analog multiplexers that operate from a single +1.6V to +4.2V supply. These devices have fast switching speeds (tON = 20ns, tOFF = 8ns), handle rail-to-rail analog signals, and consume less than 1W of quiescent power. When powered from a +2.7V supply, the MAX4780/ MAX4784 feature low 0.7 on-resistance (RON), and 0.1 R ON flatness. The digital logic input is +1.8V CMOS-logic compatible when using a single +3V supply. The MAX4780/MAX4784 are available in 16-pin TSSOP and 3mm x 3mm thin QFN packages.

Note 1: Signals on COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward 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.

The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is used in this data sheet. Note 3: -40C specifications are guaranteed by design. Note 4: RON and RON matching specifications for QFN packaged parts are guaranteed by design. Note 5: RON = RON(MAX) - RON(MIN). Note 6: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over the specified analog signal ranges. Note 7: Leakage parameters are 100% tested at TA = +85C, and guaranteed by correlation over the full rated temperature range. Note 8: Guaranteed by design. Note 9: Off-isolation = 20log10(VCOM_/VNO_), VCOM_ = output, VNO_ = input to off switch. Note 10: Between two switches. Note 11: Parts are guaranteed to 1 million cycles of operation. (Cycle = switch on switch off switch on.) Note 12: The minimum load resistance is 8. (See the Typical Application Circuit.) Note 2:

MAX4780/MAX4784
Detailed Description
The MAX4780/MAX4784 are low 0.7 (at V+ = +2.7V) on-resistance, low-voltage, quad 2:1 analog multiplexers/ demultiplexers that operate from a +1.6V to +4.2V single supply. CMOS switch construction allows switching analog signals that are within the supply voltage range (GND to V+). When powered from a +2.7V supply, the 0.7 RON allows high continuous currents to be switched in a variety of applications.
Typical Application Circuit
RING TONE/ MELODY IC
MAX4780
Applications Information
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, followed by NO_, NC_, or COM_. Although it is not required, power-supply bypassing improves noise margin and prevents switching noise propagation from the V+ supply to other components. A 0.1F capacitor, connected from V+ to GND, is adequate for most applications.

Logic Inputs
The MAX4780/MAX4784 logic inputs can be driven up to +4.2V regardless of the supply voltage. For example, with a +1.8V supply, A_ and EN may be driven low to GND and high to +4.2V. Driving A_ and EN rail-to-rail minimizes power consumption. Drive EN low to enable the COM_ outputs. When EN is high, the COM_ outputs are high impedance. resistance (see the Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be used as either inputs or outputs.
Layout
High-speed switches require proper layout and design procedures for optimum performance. Reduce stray inductance and capacitance by keeping traces short and wide. Ensure that bypass capacitors are as close to the device as possible. Use large ground planes where possible.
Analog Signal Levels
Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in on-
