Overview
The 74LVC1G125GW/DG125, produced by NXP USA Inc., is a single, non-inverting buffer/bus driver with a 3-state output. This device is designed to operate in a wide supply voltage range from 1.65 V to 5.5 V, making it versatile for use in mixed 3.3 V and 5 V environments. The 3-state output feature allows the output to enter a high-impedance state when a HIGH-level is applied to the output enable (OE) pin. This component is particularly useful for applications requiring signal buffering and level translation.
