... 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 ...
