Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-24 package and tape-and-reel packaging configuration. Confirm that the operating temperature range meets the -40°C to +85°C requirement for your application environment. Ensure compatibility with the target system's voltage levels, specifically the support for 5-V inputs with 3.3-V VCC operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer with registration is required between 3.3-V and 5-V domains. It is suitable for designs needing low power consumption and high noise immunity. Consider the TVSOP-24 package constraints regarding board space and thermal dissipation. Verify that the propagation delay characteristics align with the system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH series of low-voltage CMOS logic devices from Texas Instruments. The LVTH family combines ABT (Advanced Bipolar-CMOS Technology) performance with low-voltage operation. Similar parts in the series include the SN74LVTH646DW, which offers the same functionality in a SOIC-24 package. These devices are widely used in embedded systems and industrial control applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVTH646DW is a pin-compatible alternative in a SOIC-24 package. Verify package dimensions and thermal properties before substitution. Other registered bus transceivers may require external control logic or differ in drive strength.
