DESCRIPTION

The 74VHCT00A is an advanced high-speed

CMOS QUAD 2-INPUT 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.

Power down protection is provided on all inputs

and outputs 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.
