The 74VHCT27A is an advanced high-speed CMOS TRIPLE 3-INPUT NOR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
The internal circuit of the 74VHCT27A 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.
All inputs and outputs of the 74VHCT27A are equipped with protection circuits against static discharge,giving them 2KV ESD immunity and transient excess voltage.
