Product Overview
The SN74LVC1G38DPWR is a single 2-input positive-NAND gate with open-drain output from Texas Instruments. Designed for 1.65-V to 5.5-V VCC operation, this device provides the function Y = A ● B with an open-drain output that requires a pull-up resistor. The open-drain configuration allows wired-AND connections and level shifting. The device is available in a ultra-small 5-X2SON (0.8 mm x 0.8 mm) package, ideal for space-constrained applications.
