74VHC4066
Quad Analog Switch
General Description
These devices are digitally controlled analog switches uti-
lizing advanced silicon-gate CMOS technology. These
switches have low “on” resistance and low “off” leakages.
They are bidirectional switches, thus any analog input may
be used as an output and visa-versa. Also the 4066
switches contain linearization circuitry which lowers the
“on” resistance and increases switch linearity. The 4066
devices allow control of up to 12V (peak) analog signals
with digital control signals of the same range. Each switch
has its own control input which disables each switch when
low. All analog inputs and outputs and digital inputs are
protected from electrostatic damage by diodes to V
CC
and
ground.
