Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CAE' corresponds to the Pb-free & Green 48-pin 173 mil wide plastic TSSOP package as documented in the ordering information. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the operating environment remains within the specified industrial temperature range of -40°C to +85°C for reliable performance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional bus transceiver is required for mixed voltage environments. It is suitable for designs needing 5V tolerance on inputs while operating at 3.3V. Consider the 48-pin TSSOP package constraints and ensure adequate PCB space for the 173 mil width. Verify that the propagation delay characteristics meet the timing requirements of your specific bus interface protocol.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LPT series of fast CMOS transceivers from Diodes Incorporated (formerly Pericom). It is functionally similar to other 16-bit bus transceivers but specifically optimized for 3.3V operation with 5V tolerance. The CAE suffix denotes the specific package variant and environmental compliance status.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for alternative 16-bit bidirectional transceivers with similar pinouts and voltage tolerances. Ensure any substitute maintains the 5V input tolerance and 3.3V supply compatibility. Verify package dimensions match the 48-pin TSSOP form factor to avoid mechanical integration issues.
