74HC126

The 74HC126 is a high-speed CMOS integrated circuit designed for digital logic applications. It provides four independent bus-buffer gates with individual output enable controls and high-impedance 3-state outputs, enabling flexible signal control and safe bus sharing in multi-device systems. Four independent buffer gates with separate output enable controls for flexible signal management Operating voltage range: 2V to 6V for compatibility with various logic families Maximum propagation delay of 12 nanoseconds at 5V for fast switching performance High-impedance 3-state outputs to prevent bus contention when outputs are disabled Operating temperature range from -55°C to 125°C for use in diverse environmental conditions Built with advanced CMOS technology, the 74HC126 minimizes power consumption while maintaining rapid signal transitions and consistent performance at high frequencies. The inclusion of separate enable controls for each buffer gate adds design flexibility compared with earlier bus-buffer devices, allowing precise control over individual signal lines and simplifying complex logic arrangements. Typical applications include bus isolation, signal buffering, and situations requiring multiple devices to share a common communication line without interference. The device’s combination of low power draw, high speed, and robust temperature tolerance makes it suitable for a wide range of modern electronic circuit designs.
