SN74HC125DBR

The SN74HC125DBR is a high-speed quadruple buffer IC from Texas Instruments, featuring independent buffers with 3-state outputs. Each gate performs the Boolean function Y = A in positive logic. This device is built on the HC technology family and offers a wide operating voltage range from 2V to 6V, making it suitable for various applications.

Key electrical specifications include a maximum output current (IOL) of 6 mA and a maximum output current (IOH) of -6 mA. The maximum supply current is 80 µA. The input type is Standard CMOS, and the output type is 3-State. Features include balanced outputs and an input clamp diode, contributing to its very high speed operation with typical propagation delays between 5-10 ns.

This buffer IC is designed for operation within an ambient temperature range of -40°C to 85°C. It is supplied in a 14-SSOP package, suitable for surface mounting. The device supports fanout up to 10 LSTTL loads and offers significant power reduction compared to LSTTL logic ICs. It contains four independent buffers, each with a single bit input and output.

Applications for the SN74HC125DBR include signal buffering and level shifting in digital circuits. Its 3-state output capability allows it to be connected to a common bus line, enabling multiple devices to share data lines efficiently. The wide operating voltage range and robust features make it a versatile component for digital system design.
