The 74VHC20 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 of the 74VHC20 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.

All inputs and outputs of the 74VHC20 are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
