SN74ACT245NSR Description

Short technical summary and product information.

The Texas Instruments SN74ACT245NSR is an octal bus transceiver designed for asynchronous two-way communication between data buses. This device features a VCC operation range of 4.5V to 5.5V, with inputs capable of accepting voltages up to 5.5V. The maximum propagation delay is rated at 8ns at 5V, and the inputs are TTL-voltage compatible.

 

This transceiver is suitable for applications such as Pro Audio, Video and Signage, Appliances, and Factory Automation and Control. It comes in a 20-SOIC package and is designed for surface mount applications. The device offers 8 channels with 8 bits per element, providing a robust solution for data bus interfacing.

 

Key electrical characteristics include an output current of 24mA (source and sink) and TTL-compatible inputs. The 3-state output capability allows for efficient bus management. The operating temperature range is -40°C to 85°C (TA).
