Single 2-Input NOR Gate with Open Drain Output

The MC74VHC1G03 / MC74VHC1GT03 is a 2−input NOR Gate with an open drain output in tiny footprint packages. The input structures provide protection when voltages up to 5.5 V are applied, regardless of the supply voltage. This allows the device to be used to interface 5 V circuits to 3 V circuit
