SN74ACT126PWR TI Buffer/Driver | 14-TSSOP | 4.5V-5.5V, 24mA

Product Overview

The SN74ACT126PWR is a quadruple bus buffer gate with 3-state outputs from Texas Instruments. It features independent line drivers with 3-state outputs, designed for driving bus lines or buffer memory address registers. Each output is disabled when the associated output-enable (OE) input is low. The device operates over a wide voltage range of 4.5V to 5.5V and is characterized for operation from -40°C to 85°C. Housed in a 14-pin TSSOP package, it offers a compact solution for high-speed signal buffering in digital systems.
