74HC126D

The 74HC126D is a quad non-inverting buffer/line driver with 3-state outputs, part of the 74HC family of high-speed CMOS devices. Each of the four independent buffers is equipped with its own output enable pin, allowing for greater control of data flow on shared bus systems. When the output enable pin is high, the corresponding output is disabled, resulting in a high-impedance state, which effectively disconnects it from the circuit. This feature is crucial for preventing conflicts on a shared data bus.
The 74HC126D operates with a supply voltage range of 2V to 6V, making it suitable for a variety of digital applications. Its high-speed performance is complemented by low power consumption, characteristic of CMOS technology. The device is commonly used in applications involving signal buffering, data routing, and interfacing between different logic levels. The 74HC126D is available in various package types, such as SOIC and TSSOP, making it adaptable to different PCB designs. It is favored for its reliability, ease of use, and integration into bus-oriented systems.
