Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix (e.g., DGGR) against the manufacturer's datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering part number with official Texas Instruments documentation to avoid confusion with similar ALVC series variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3 V logic family is required for high-speed bidirectional data transfer. The integrated register functionality makes it suitable for applications demanding data synchronization. Verify that the load capacitance and drive strength requirements align with the target bus architecture before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVCH (Advanced Low-Voltage CMOS High-Speed) family, designed for low power consumption and high-speed operation at 3.3 V. It complements other 16-bit transceivers in the 74xx series, offering a balance of performance and integration for complex digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ALVCH16646DGGR as a potential pin-compatible alternative with identical electrical characteristics. Verify functional equivalence with SN74LVC16646 if 5 V tolerance is not required, noting differences in supply voltage ranges.
