DESCRIPTION
The 74V2T00 is an advanced high-speed CMOS
DUAL 2-INPUT NAND GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS tecnology.
The internal 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
used to interface 5V to 3V.
