74HC125

The 74HC125 is a quad buffer/line driver integrated circuit that provides four independent non‑inverting buffers with three‑state outputs, engineered for high‑speed CMOS logic applications. It delivers reliable signal gating and isolation while maintaining minimal propagation delay, making it suitable for a wide range of digital designs where rapid, controlled signal transfer is required. Key characteristics include an operating voltage range of 2V to 6V for compatibility with multiple supply systems, a typical propagation delay of 14 ns to support timing‑sensitive circuits, and high noise immunity rated at 28% of VCC to preserve signal integrity in electrically noisy environments. The three‑state output capability enables effective bus sharing and signal multiplexing, and the device’s low quiescent current consumption contributes to energy‑efficient implementations. Four independent non‑inverting buffers with three‑state outputs. Operating voltage range: 2V to 6V for versatile supply compatibility. Typical propagation delay: 14 ns for fast switching operations. High noise immunity (28% of VCC) for robust performance. Low quiescent current for reduced power draw in standby conditions. Compared with earlier models and common industry devices, the 74HC125 emphasizes improved speed and power efficiency while preserving compatibility with standard logic levels.
