Description

The 74VHCT20A is an advanced high-speed CMOS DUAL 4-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 of the 74VHCT20A 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 of the 74VHCT20A are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
