Overview
The SN74LVC1G125DBVRG4, produced by Texas Instruments, is a single bus buffer gate with 3-state output. This device is part of the LVC (Low-Voltage CMOS) family and is designed to operate over a wide voltage range from 1.65 V to 5.5 V. It features a single buffer gate with output enable control, performing the Boolean function Y = A. The device is fully specified for partial-power-down applications using Ioff circuitry, which prevents damaging current backflow when the device is powered down.
