Overview
The 74LVC1G125QW5-7, produced by Diodes Incorporated, is an automotive-compliant single, non-inverting buffer/bus driver with a 3-state output. This device is designed to operate within a wide power supply range of 1.65V to 5.5V, making it suitable for mixed-voltage environments. The inputs are tolerant up to 5.5V, and the device supports partial power-down mode using IOFF circuitry, which prevents damaging current backflow when the device is powered down.
