SN74AHCT125BQAR TI Buffer/Driver | 14-WQFN (3x2.5) | 4-ch, 5V, 8mA

Product Overview

The SN74AHCT125BQAR from Texas Instruments is a quad bus buffer gate with 3-state outputs, designed for 5V CMOS logic systems. It features independent line drivers with 3-state outputs, each with its own output enable input (OE). When OE is low, the output is enabled; when high, the output is in high-impedance state. This device is ideal for driving bus lines or buffering memory address registers. It operates over a wide voltage range of 4.5V to 5.5V and offers high drive capability of ±8 mA at 5V. The package is a 14-pin WQFN (3x2.5 mm) for space-constrained applications.
