SN74HC126NSR TI Buffer/Driver | 14-SO | 4-ch, 2V-6V, 7.8mA

Product Overview

The SN74HC126NSR is a high-speed quad bus buffer gate with 3-state outputs from Texas Instruments. It features four independent buffer gates with non-inverting outputs, each with its own output enable input. When the output enable (OE) is low, the output is disabled (high-impedance state). The device operates over a wide supply voltage range of 2V to 6V, making it suitable for a variety of logic-level applications. Housed in a 14-pin SO package, it is ideal for space-constrained designs.
