Procurement Notes

This component is classified as obsolete and scheduled for discontinuation by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or existing stock. Verify end-of-life status and lead times carefully before finalizing procurement plans due to limited supply chain support.

Selection Notes

Select this part only if compatibility with legacy HOTLink infrastructure is required. Ensure the design accommodates the 28-pin PLCC footprint and 4.5V to 5.5V power requirements. Consider migration strategies to newer components given the obsolete status. Validate signal integrity specifications against system requirements prior to integration.

Part Context

The CY7B923 series belongs to Infineon's HOTLink family of serial transceivers. This specific model serves as the transmitter counterpart within the pair. It enables point-to-point serial communication links. The series was widely used in telecommunications and storage networking equipment requiring reliable high-speed data transfer over short distances.

Replacement Considerations

Refer to Infineon's official migration guide for transitioning from CY7B923/CY7B933 to HOTLink II components. Consult datasheets for compatible replacements such as the CY7C923 series. Verify pinout and electrical parameter compatibility when selecting substitute parts.
