概述

Description

The SN74HC125DR is a quad buffer/driver with three-state outputs from Texas Instruments, part of the HC (High-speed CMOS) logic family. It features four independent buffer/driver circuits, each with a tri-state output that can be enabled or disabled. This allows for efficient control of data flow in digital circuits, making it ideal for applications such as bus-oriented systems.
Operating over a supply voltage range of 2V to 6V, the SN74HC125DR offers high-speed performance with propagation delays typically around 10 ns at 5V. It can drive up to 15 capacitive loads, making it suitable for driving LEDs and interfacing with microcontrollers.
The device is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package), which is compact and ideal for space-constrained applications. Key features include low power consumption, high noise immunity, and compatibility with other logic families. Overall, the SN74HC125DR is a versatile component for managing digital signals in various electronic designs.
