74HC125N (Quad 3-State Buffer)

Overview

The 74HC125N is a high-speed CMOS quad 3-state buffer IC, essential for bus-oriented systems. Each of its four independent buffers features a non-inverting output with a 3-state enable control, allowing outputs to be effectively disconnected from the bus when not in use. This makes it ideal for multiplexing data lines, address decoding, and driving shared buses in digital circuits.

Key Features

• Quad 3-State Buffers: Four independent non-inverting buffers with individual output enables.
• Wide Operating Voltage: Operates from 2V to 6V, compatible with TTL and CMOS logic levels.
• High-Speed Performance: Propagation delay as low as 17 ns at 6V, ensuring fast data transfer.
• Low Power Consumption: CMOS technology minimizes power usage, ideal for battery-powered projects.
• Standard 14-Pin DIP Package: Easy to use on breadboards and PCBs, perfect for prototyping.

Technical Specifications

• Number of Gates: 4
• Logic Family: 74HC (High-Speed CMOS)
