## Description

The 74ACT245M is an advanced high-speed CMOS octal bus transceiver from STMicroelectronics, fabricated with sub-micron silicon gate technology. This device is designed for two-way asynchronous communication between data buses, with the direction of data transmission determined by the DIR input. The enable input (G) can be used to disable the device, effectively isolating the buses.

Key electrical characteristics include a typical propagation delay of 5.4ns at 5V, low power dissipation with a maximum quiescent current of 4 μA at 25°C, and compatibility with TTL outputs. The operating voltage range is from 4.5V to 5.5V. It offers symmetrical output impedance with |IOH| = IOL = 24mA (MIN) and balanced propagation delays.

All inputs and outputs are equipped with protection circuits against static discharge, providing 2KV ESD immunity. The 74ACT245M is pin and function compatible with the 74 Series 245 and is suitable for interfacing High Speed CMOS systems with TTL, NMOS, and CMOS output voltage levels.

This transceiver is available in an SOP package, suitable for surface mounting. It is designed for applications requiring high-speed data transfer and bus isolation.
