Product Description

The 74HC245D is an Octal Bus Transceiver from the HC Series Logic IC family, designed for bidirectional data transfer between 8-bit buses. Featuring eight input/output lines, it enables direct interfacing with microprocessors, memory modules, or peripheral devices. Operating within a 2V to 6V voltage range, this 3-state device supports high-speed parallel communication while maintaining low power consumption. Its temperature tolerance (-40°C to +125°C) suits industrial automation, automotive systems, and embedded electronics. Key advantages include symmetrical output impedance, balanced propagation delays, and robust noise immunity. However, signal integrity may degrade in high-frequency applications without proper termination. The transceiver's direction control (DIR) and output enable (OE) pins simplify bus management in multidrop or shared-line architectures. Compatible with TTL levels, it integrates seamlessly into mixed-voltage systems.
