Overview
The SN74ABT126PW is a quadruple bus buffer gate produced by Texas Instruments. This integrated circuit features independent line drivers with 3-state outputs, making it suitable for various digital signal buffering applications. Each output is disabled when the associated output-enable (OE) input is low, allowing for flexible control over the output states. The device operates within a voltage range of 4.5 V to 5.5 V and is available in a TSSOP (PW) package with 14 pins, supporting an operating temperature range of -40°C to 85°C.
