DESCRIPTION

The 74V1T02 is an advanced high-speed CMOS
SINGLE 2-INPUT NOR GATE fabricated with
sub-micron silicon gate and double-layer m etal
wiring C

2

MOS technology.
The int ernal circuit is composed of 3 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
usedto interface 5V to 3V.
