Datasheet
74VHCT08A is an advanced high-speed CMOS QUAD 2-INPUT AND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. The internal circuit is composed of 2 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.
