... These devices have fast switching speeds (t = 20ns rail-to-rail analog signals, and consume less than 1µW of quiescent power. When powered from a +2.7V supply, the MAX4780/ MAX4784 feature low 0.7Ω on-resistance (R 0.1Ω R flatness. The digital logic input is +1.8V ON CMOS-logic compatible when using a single +3V supply. ...

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 ...

... Detailed Description The MAX4780/MAX4784 are low 0.7Ω ( +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 0.7Ω R allows high continuous currents to be switched in a variety of applications ...

... Low-Voltage, Quad 2:1 Analog Multiplexers 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 ...
