CD74HC125E TI High-Speed CMOS Quad Bus Buffer Gate | 14-PDIP | 2V to 6V, 8mA Output

Product Overview

The CD74HC125E from Texas Instruments is a high-speed CMOS quad bus buffer gate with three-state outputs. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The device features four independent buffer gates with non-inverting outputs, each controlled by an output enable input (OE). When OE is low, the output is enabled; when high, the output is in high-impedance state. This allows multiple outputs to be connected to a common bus line. The CD74HC125E is offered in a 14-pin PDIP package, ideal for through-hole PCB assembly.
