DESCRIPTION The 74VHCT03A is an advanced high-speed CMOS QUAD 2-INPUT OPEN DRAIN 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. This device can, with an external pull-up resistor, be used in wired AND configuration. This device can also be used as a led driver and in any other application requiring a current sink. 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 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.
