Overview
The SN74LVC1G38DBVR is a single 2-input NAND gate with an open-drain output, designed and manufactured by Texas Instruments. This device operates within a wide supply voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It performs the Boolean function Y = A × B or Y = A + B in positive logic. The SN74LVC1G38DBVR is fully specified for partial-power-down applications using Ioff circuitry, which disables the outputs when the device is powered down to prevent current backflow and potential damage.
