SN74ABT245BNSR Description

Short technical summary and product information.

The SN74ABT245BNSR from Texas Instruments is an octal bus transceiver featuring 3-state outputs, designed for asynchronous data transfer between buses. The direction of data flow is controlled by the DIR input, and the OE input can disable the device, isolating the buses.

 

This transceiver operates within a voltage range of 4.5V to 5.5V and is specified for an operating temperature range of -40°C to 85°C. It offers high-drive outputs with capabilities of -32mA for IOH and 64mA for IOL. The device also supports hot-insertion with Ioff and power-up 3-state functionality, preventing damaging current backflow during power transitions.

 

Packaged in a 20-SOIC format, the SN74ABT245BNSR is suitable for surface mount applications. Its latch-up performance exceeds 500 mA per JEDEC Standard JESD 17, and ESD protection exceeds 2000V for the Human-Body Model and 200V for the Machine Model.

 

Key electrical characteristics include typical output ground bounce of less than 1V at 5V VCC and 25°C TA. The device is designed for reliable operation in various environments, meeting stringent performance standards.
