SN74ABTH245DW Description

Short technical summary and product information.

The SN74ABTH245DW from Texas Instruments is an octal bus transceiver designed for asynchronous communication between data buses. It supports 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 allows for disabling the device, effectively isolating the buses.

 

This transceiver operates with a voltage range of 4.5V to 5.5V and has an operating temperature range of -40°C to 85°C. Key electrical features include high-drive outputs with 32mA sourcing and 64mA sinking capabilities, 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.

 

The SN74ABTH245DW is available in a 20-SOIC surface mount package. Its design ensures latch-up performance exceeds 500 mA per JESD 17 and typical output ground bounce is less than 1V at VCC = 5V, TA = 25°C. This makes it suitable for applications requiring reliable data transfer and bus isolation.
