The MC74VHC1GT32DBVT1G-Q is a single 2-input OR gate with TTL-level input thresholds, provided in a compact SC-74A package. It is designed to operate with a VCC supply from 2.0 V to 5.5 V and has a typical propagation delay of 3.5 ns at 5 V. The device's inputs and outputs are over-voltage tolerant up to 5.5 V, which allows the device to be used to interface 5 V circuits to 3 V circuits. Features like IOFF support for partial power-down protection make this gate ideal for applications involving supply voltage mismatch, battery backup, and hot insertion.
