Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix 'RG4', which indicates RoHS compliance and green package status. Confirm the 'A' designator signifies the specific manufacturing revision. Ensure the SSOP-20 package matches your PCB footprint requirements. Cross-reference the datasheet version to confirm pinout compatibility before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving an octal bus requires robust current handling at 3.3V logic levels. The LVTH series offers superior performance over standard LVT devices regarding speed and noise immunity. Consider the SSOP-20 package constraints regarding thermal dissipation and board space. Verify that the input voltage levels are compatible with the source logic family to ensure reliable switching thresholds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A family of octal buffers. It is functionally similar to the SN74LVTH244APWRG4 but differs in package type, utilizing SSOP-20 instead of TSSOP-16. It serves as a bridge component in mixed-voltage digital systems, enabling signal integrity maintenance across varying power domains while providing necessary isolation and drive strength.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVTH244ADBR is a direct functional equivalent without the RoGS suffix. Check for SN74LVTH244APWRG4 if TSSOP-16 packaging is acceptable. Verify pin-to-pin compatibility with other octal bus transceivers from the same manufacturer before substitution.
