Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DGGR against official Texas Instruments documentation to confirm the TSSOP-48 or TVSOP-56 package type and reel quantity. Ensure the part number matches the exact pin count and channel configuration required for the target circuit design. Cross-reference the datasheet revision date to confirm electrical characteristics and packaging details remain consistent with current manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems with distinct voltage domains, such as 1.2V and 3.3V logic levels. The dual-supply architecture allows independent voltage control for Port A and Port B. Consider the 20-bit width and 380 Mb/s speed for high-bandwidth requirements. Verify that the TVSOP-56 package fits the available PCB footprint and thermal constraints of the application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC2T245 family of bus transceivers. It shares functional similarities with parts like the SN74AVC16T245 but offers increased bit capacity. The AVC series is characterized by its ability to handle wide voltage ranges while maintaining low power consumption. It serves as a bridge for digital signals in mixed-voltage electronic systems.
