SN74ABT543APWR Description

Short technical summary and product information.

The SN74ABT543APWR from Texas Instruments is an octal registered transceiver featuring 3-state outputs. This device is built using state-of-the-art EPIC-IIB BiCMOS design, which significantly reduces power dissipation. It contains two sets of D-type latches for temporary data storage, allowing data flow in either direction.

 

Key electrical characteristics include a wide operating voltage range of 4.5V to 5.5V, high-drive outputs with IOL of 64mA and IOH of -32mA, and a typical output ground bounce of less than 1V at 5V and 25°C. ESD protection exceeds 2000V per MIL-STD-883, Method 3015.

 

Designed for surface mounting, the SN74ABT543APWR comes in a 24-TSSOP package. It is characterized for operation within an ambient temperature range of -40°C to 85°C. The transceiver offers features like over-voltage tolerant inputs and partial power-down capabilities (Ioff), making it suitable for various digital interface applications requiring high-speed data transfer and reliable signal integrity.
