4HCT245D - Octal Bus Transceiver, SOP-20, 5V CMOS Logic

The 74HCT245D is a high-speed CMOS octal bus transceiver, designed to facilitate bidirectional data flow between two buses with low power dissipation. Built with CMOS technology, it supports TTL-compatible inputs and outputs, allowing seamless interfacing with TTL, NMOS, and CMOS logic levels. This device enables two-way asynchronous communication between data buses, with control provided by a direction input (DIR) and an output enable (OE) input to disable data transmission paths when necessary.

This IC is ideal for various applications requiring data isolation and protection from electrostatic discharge, including microcontroller interfaces, digital communication systems, and industrial automation. With a balanced propagation delay, the 74HCT245D ensures reliable and consistent data transfer rates, making it suitable for high-speed computing and control applications.

Key Features :

• High-Speed Performance: Propagation delay of 11 ns at Vcc = 5.5V.
• Low Power Consumption: Operates at a quiescent supply current (Icc) of 4.0 uA.
• TTL-Compatible Inputs and Outputs: Compatible with TTL, NMOS, and CMOS logic levels.
• Balanced Propagation Delay: Provides uniform data transfer rates for reliable communication.
• 3-State Outputs: Allows isolation of the buses when disabled.
• Compact SOP-20 Package: Optimized for high-density board designs.
