Procurement Notes

Verify end-of-life status before procurement. The manufacturer has issued a discontinuance notification dated September 19, 2024. Confirm availability through authorized distributors and check for moisture sensitivity handling requirements during storage and assembly. Ensure design-in compatibility with existing system architectures prior to ordering.

Selection Notes

Select this component for applications requiring laser drivers with data rates up to 4.25 Gbps. Consider the VQFN-24 package size for board layout constraints. Verify that the 45 mA supply current fits within the system's power budget. Check thermal performance at the maximum operating temperature of 85 °C. Ensure the 3 V to 3.6 V supply range matches the available power rails in the target design.
