The 74VHCT03A is an advanced high-speed
CMOS QUAD 2-INPUT OPEN DRAIN NAND
GATE fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provides high noise
immunity and stable output.
This device can, with an external pull-up resistor,
be used in wired AND configuration. This device
can also be used as a led driver and in any other
application requiring a current sink.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
