DESCRIPTION
The 74H1G66 is an high-speed CMOS SINGLE
BILATERAL SWITCH fabricated in silicon gate
C
2
MOS
technology.
It
has
high
speed
performance combined with true CMOS low
power consumption.
The C input is provided to control the switch; the
switch is ON when the C input is held high and off
when C is held low.
