74HC245D Octal Bus Transceiver IC – 3-State – SOIC-20 – Nexperia/TI

The 74HC245D is a high-speed CMOS octal (8-bit) bidirectional bus transceiver designed for asynchronous two-way communication between data buses. Featuring non-inverting, 3-state outputs, this device provides robust bus isolation and controlled data flow, making it ideal for microcontroller, memory, and peripheral interfacing.

Operating across a wide 2.0V to 6.0V supply range, the 74HC245D supports standard CMOS logic levels with strong output drive capability of ±7.8mA at 6V. Its direction control (DIR) pin and output enable (OE) pin provide simple and flexible bus management, ensuring safe and efficient data transfer between systems.

Rated for operation from –40°C to +125°C, this IC delivers stable performance in industrial, automotive, and consumer applications. Packaged in a compact SOIC-20 surface-mount footprint, it is widely used for bus buffering, logic-level interface expansion, and general digital communication designs.
