SN74AHCT245NSR Description

Short technical summary and product information.

The Texas Instruments SN74AHCT245NSR is an octal bus transceiver designed for asynchronous two-way communication between data buses. This device operates within a voltage range of 4.5V to 5.5V and is suitable for applications requiring signal enabling or holding during controller resets.

 

Key electrical specifications include TTL-compatible inputs and 3-state CMOS outputs. The transceiver supports a current output of 8mA for both IOL and IOH. It offers very high speed operation with propagation delays typically between 5ns and 10ns.

 

Packaged in a 20-SOIC (0.209", 5.30mm Width) surface mount package, the SN74AHCT245NSR operates across a wide temperature range of -40°C to 125°C (TA). Latch-up performance exceeds 250 mA per JESD 17, ensuring robust operation.

 

This component is ideal for various digital interfacing tasks, enabling or disabling digital signals, and holding data during system resets. Its design facilitates efficient data transfer between different bus systems.
