Overview
The SN74AHC125PWR is a quadruple bus buffer gate produced by Texas Instruments. This integrated circuit is part of the 74AHC series and features independent line drivers with 3-state outputs. Each output can be disabled when the associated output-enable (OE) input is high, allowing for flexible control over data transmission. The device operates within a voltage range of 2V to 5.5V, making it versatile for various applications. It is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) and is RoHS compliant.
