DESCRIPTION
The 74V1T08 is an advanced high-speed CMOS
SINGLE 2-INPUT AND GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
The internal circuit is composed of 2 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
