DESCRIPTION
The 74V1T66 is an advanced high-speed CMOS
SINGLE BILATERAL SWITCH fabricated in
silicon gate C
2
MOS technology. It achieves high
speed propagation delay and VERY LOW ON
resistances while maintaining true CMOS low
power consumption. This bilateral switch handles
rail to rail analog and digital signals that m ay vary
across the full powe r supply range (from GND t o
V
).
CC
The C input is provided to control the switc h and
it’s c ompatible with standard TTL output; the
switch is ON (port I/O is connect ed to Port O/I)
PIN CONNECTION AND IEC LOGIC SYMBOLS
when the C input is held high and OFF (high
impedance state exists between the two ports)
when C is held low. It can b e used in m any
application as Battery Powered System, Test
Equipment. It’s available in the commercial and
extended temperature range in SOT23-5L and
SOT323-5Lpackage.
All inputs and output are equipped with protection
circuits against static discharge, giving them ESD
immunity and transient excess voltage.
