SN74ABTH245PWR Description

Short technical summary and product information.

The SN74ABTH245PWR from Texas Instruments is an octal bus transceiver designed for asynchronous communication between data buses. It features 8 channels and non-inverting, 3-state outputs, allowing data transmission from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input can disable the device, isolating the buses.

 

This transceiver operates within a voltage range of 4.5V to 5.5V and has an operating temperature range of -40°C to 85°C. Key features include high-drive outputs (-32mA IOH, 64mA IOL), bus hold on data inputs to eliminate the need for external pullup/pulldown resistors, and support for hot insertion with Ioff and power-up 3-state functionality. The device utilizes an EPIC-IIB BiCMOS design, significantly reducing power dissipation.

 

Packaged in a 20-TSSOP, the SN74ABTH245PWR is suitable for surface mount applications. Its latch-up performance exceeds 500 mA per JESD 17, and it exhibits typical output ground bounce of less than 1V at 5V and 25°C.
