DESCRIPTION

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

regard to the supply voltage. This device can be

used to interface 5V to 3V since all inputs are

equipped with TTL threshold.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
