HD74HC4066
Quad Analog Switches/Quad Multiplexers
Description
This switch has low "on" resistance and low "off" leakage. It is a bidirectional switch, thus any analog
input may be used as an output and vice-versa. Also the HD74HC4066 switch contains linearization
circuitry which lowers the "on" resistance and increases switch linearity. The HD74HC4066 device allows
control of up to 12 V (peak) analog signals with digital control signals of the same range. Each switch has
its own control input which disables each switch when low.
