Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process. Cross-reference the part number with the latest datasheet revision to validate pinout and electrical characteristics.

Flip Flops Selection Notes

Select this component when designing systems requiring 3.3-V logic compatibility with high-speed performance. The LVTH series offers superior switching speeds compared to standard HCT devices while maintaining TTL-compatible input thresholds. Ensure the application voltage remains within the 2.7 V to 3.6 V range to guarantee reliable operation and meet the specified timing constraints.

Flip Flops Part Context

This part belongs to the SN74LVTH273 family of octal D-type flip-flops. It is distinct from the SN74HCT273 due to its lower voltage operation and faster switching speeds. The device is manufactured by Texas Instruments and is available in a 20-pin Small Outline Integrated Circuit (SOIC) package suitable for surface-mount technology applications.

Flip Flops Replacement Considerations

SN74LVTH273NSRG4 is a confirmed equivalent part number representing the same functional device with potential minor packaging or compliance variations.
