Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS certification status as per manufacturer documentation. Confirm the package designation matches the 56-TSSOP physical dimensions. Ensure the operating temperature range aligns with system requirements, typically spanning from -40°C to +85°C for this industrial-grade component.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with three-state outputs is required for bidirectional communication. The ABT series offers high-speed performance suitable for demanding digital interfaces. Consider the 56-pin TSSOP package constraints for PCB layout. Verify that the 4.5 V to 5.5 V supply voltage range matches the target system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ABT family of high-speed CMOS logic devices. The 74ABT16543 variant specifically provides registered transceiver functionality. It is distinct from unbuffered variants like the 74ABT16540, which lacks internal latching. The device serves as a key interface element in complex digital systems requiring data storage at the bus level.
