Quad Analog Switch
74VHC4066 Quad Analog Switch
April 1994
Revised January 2000
General Description
These devices are di gitally controlled a nalog switches utilizing advanced silicon-gate CMOS technology. These
switches have low “on” resista nce and low “off” leakages.
They are bidirectional switches, thus any analog inp ut m ay
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 u p to 12V (peak) analog signals
with digital control signals of th e same r ange. Each switch
has its own control input which disables ea ch switch when
low. All analog inputs and outpu ts and digital inputs are
protected from electro static damage by diode s to V
ground.

Note 4: For a pow er supply of 5V ± 10% the worst case on resistance (RON) occurs for VHC at 4.5V. Thus the 4.5V values should be used when designing
with this supply. Worst case V
for CMOS at the higher voltage and so the 5. 5V values should be used.
