概要

Description

The SN74LVC245ADBR is an 8-bit transceiver IC manufactured by Texas Instruments, part of the LVC family. It is designed for asynchronous two-way communication between data buses, allowing data transfer in either direction with separate control lines for direction and output enable. This device operates with a voltage range of 1.65V to 3.6V, making it suitable for both 3.3V and 5V systems, though it’s optimized for 3.3V.
Key features include low power consumption with a typical quiescent current of approximately 10 µA, and the ability to drive up to 24 mA outputs, ensuring compatibility with a variety of loads. Its inputs are tolerant up to 5.5V, allowing it to interface with higher-voltage signals. The SN74LVC245ADBR is housed in a small-outline package (SOP), making it ideal for space-constrained applications.
This transceiver is commonly used in digital systems for buffering, data multiplexing, and level translation. It is favored for its high speed, low power draw, and robust performance in various applications.
