DESCRIPTION
The 74V1T66 is an high-speed CMOS SINGLE
BILATERAL SWITCH fabricated in silicon gate
C2MOS technology. It achieves high speed
propagation
delay
and
VERY
LOW
ON
resistances while maintaining true CMOS low
power consumption. This feature makes this part
ideal
for
battery-powered
equipment.
This
bilateral switch handles rail to rail analog and
digital signals that may vary across the full
power-supply range (from Vcc to Ground).
The C input is provided to control the switch and
it's compatible with standard TTL output; the
switch is ON when the C input is held high and off
when C is held low. It can be used in many
application as Battery Powered System, Audio
Signal Routing, Communications System, Test
Equipment. It's available in the commercial
temperature range in SOT23-5L and SC-70-5L
package.
