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.

Note 4:
For a power supply of 5V
±
10% the worst case on resistance (R
ON
) occurs for VHC at 4.5V. Thus the 4.5V values should be used when designing
with this supply. Worst case V
IH
and V
IL
occur at V
CC
=
5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage current occurs
for CMOS at the higher voltage and so the 5.5V values should be used.
Note 5:
At supply voltages (V
CC
– GND) approaching 2V the analog switch on resistance becomes extremely non-linear. Therefore it is recommended that
these devices be used to transmit digital only when using these supply voltages.
