Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple variants. Confirm the specific temperature grade and lead finish requirements against the official Package Option Addendum. Ensure compatibility with the intended PCB footprint for the TVSOP-48 configuration before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide data transfer with low-voltage operation down to 1.65 V. It is suitable for applications needing 5-V tolerance on inputs without external level shifters. Consider the TVSOP-48 package constraints regarding thermal dissipation and board space availability compared to TSSOP or SSOP alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC16245A series within the Texas Instruments Widebus family. The 'DGVR' suffix specifically denotes the TVSOP (Thin Very Small Outline Package) with 48 pins and reel packaging. It shares functional characteristics with other LVC series transceivers but is optimized for high-density surface-mount applications.
