SN74ABT16543DLR Description

Short technical summary and product information.

The Texas Instruments SN74ABT16543DLR is a 16-bit registered transceiver designed for high-speed data flow. It belongs to the Widebus family and utilizes an EPIC-IIB BiCMOS design for reduced power dissipation.

 

This transceiver operates within a voltage range of 4.5V to 5.5V and functions across an industrial temperature range of -40°C to 85°C. It offers high-drive outputs with capabilities of -32mA I OH and 64mA I OL. The device contains two sets of D-type latches for temporary data storage, allowing it to be configured as two 8-bit transceivers or one 16-bit transceiver.

 

Packaged in a 56-SSOP (0.295", 7.50mm Width), the SN74ABT16543DLR is suitable for surface mounting. Its flow-through architecture is optimized for PCB layout, and distributed VCC and GND pin configurations minimize switching noise. Separate latch-enable and output-enable inputs provide independent control for each data direction.

 

Key features include latch-up performance exceeding 500 mA per JEDEC standard JESD-17 and typical V OLP (Output Ground Bounce) below 1V at VCC = 5V, TA = 25°C.
