SN74AC126BQAR TI Buffer/Driver | 14-WQFN (3x2.5) | 4-ch, 2V-6V, 24mA

Product Overview

The SN74AC126BQAR from Texas Instruments is a quadruple bus buffer gate with 3-state outputs, designed for 2V to 6V VCC operation. It features four independent buffer gates with non-inverting outputs, each controlled by an output enable (OE) input. When OE is low, the corresponding output is in a high-impedance state. This device is ideal for driving bus lines or buffering memory address registers, offering high drive capability (up to 24mA at 5V) and low power consumption. Housed in a compact 14-WQFN (3x2.5mm) package, it is suitable for space-constrained applications.
