SN74HC245 IC Bus transceiver DIP-20 SN74HC245

Product Overview

The SN74HC245, manufactured by Texas Instruments, is an octal bus transceiver designed for asynchronous, two-way communication between data buses. This CMOS-based device provides low power consumption (80-μA maximum $I_{CC}$) and operates across a wide voltage range of 2V to 6V. It features 3-state outputs capable of driving bus lines directly or up to 15 LSTTL loads, making it suitable for applications such as servers, PCs, network switches, and telecom infrastructures.

The device facilitates data transmission between an "A" bus and a "B" bus, with the direction of flow controlled by the Direction-Control (DIR) input. Additionally, an Output-Enable ($\overline{\text{OE}}$) pin allows the user to disable the device, effectively isolating the buses from each other.
