The MC74VHC1G09 is an advanced high speed CMOS 2-input AND gate with open drain output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The internal circuit is composed of three stages, including an open drain output which provides the capability to set output switching level. This allows the MC74VHC1G09 to be used to interface 5V circuits to circuits of any voltage between VCC and 5.5V using an external resistor and power supply. The MC74VHC1G09 input structure provides protection when voltages up to 5.5V are applied, regardless of the supply voltage.
