Overview
The SN74LVC1G38DBVRE4 is a single 2-input NAND gate with an open-drain output, manufactured by Texas Instruments. This device is part of the LVC (Low-Voltage CMOS) family and is designed for operation over a wide voltage range from 1.65 V to 5.5 V. It is suitable for various applications requiring low power consumption and high performance.
The device features a small footprint, available in several package options such as SOT-23, SC70, SON, DSBGA, and X2SON, making it versatile for different design needs. It also includes Ioff circuitry, which disables the outputs when the device is powered down, preventing current backflow and potential damage.
