SN74ABT543ADW Description

Short technical summary and product information.

The Texas Instruments SN74ABT543ADW is an octal registered transceiver featuring 3-state outputs. This component utilizes state-of-the-art EPIC-IIB BiCMOS design, significantly reducing power dissipation. It is characterized for operation from -40°C to 85°C (TA).

 

The transceiver contains two sets of D-type latches for temporary data storage in either direction. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs allow independent control for each register. The A-to-B enable (CEAB) input must be low to enter data from A or output data from B. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the data at the output of the A latches.

 

Key electrical characteristics include a wide operating voltage range of 4.5V to 5.5V, high-drive outputs capable of -32mA IOH and 64mA IOL, and ESD protection exceeding 2000V per MIL-STD-883. The device offers typical output ground bounce of less than 1V at VCC = 5V, TA = 25°C.

 

Available in a 24-SOIC package, the SN74ABT543ADW is suitable for surface mount applications. Its robust design and features make it a reliable choice for various digital communication and data storage systems.
