Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix designation against official AMD documentation to confirm exact speed grades and package variations. Ensure compliance with relevant environmental standards as the base part may not be RoHS compliant. Confirm that the SOIC-24 footprint matches your PCB layout requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring reliable 8-bit bidirectional data transmission with built-in error checking. The CMOS technology ensures compatibility with standard logic families while offering low power consumption. Consider the 70 °C operating limit when evaluating thermal management strategies for enclosed environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Advanced Micro Devices CMOS logic family, specifically engineered for bus interface applications. It serves as a critical component for managing data flow directionality and integrity in digital systems. The inclusion of parity functions distinguishes it from standard transceivers by adding a layer of data validation directly at the physical interface level.
