Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix AZQLR corresponds to the 56-pin Microstar Junior BGA package. Confirm the operating voltage range matches system requirements of 1.65 V to 3.6 V. Ensure input compatibility with 5.5 V signals if interfacing with higher voltage logic. Check for RoHS compliance status in official documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit data latching with low power consumption. It is suitable for applications needing 5.5 V tolerant inputs while operating at lower core voltages. Consider the BGA package constraints for PCB layout and thermal management during selection.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments Widebus family of 16-bit registered transceivers. It shares functional similarities with other LVCH series devices but is distinguished by its specific BGA packaging and voltage tolerance characteristics. It serves as a bridge between low-voltage processors and peripheral devices.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVCH16543ADL variants for SSOP-56 packaging alternatives. Verify pinout compatibility before substituting with other 16-bit registered transceivers from the same manufacturer.
