• High-speed performance with a typical propagation delay of 17.1 ns under standard loading conditions
• Robust output drive capability delivering ±8 mA current for reliable signal transmission

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in communication interfaces
• General-purpose storage elements in microprocessor-based systems
• Timing and synchronization logic in digital control applications

Procurement Notes

Verify the specific suffix SJ against the official onsemi datasheet to confirm the SOP-20 package variant. Confirm RoHS compliance status through the manufacturer's material composition documents. Check current lifecycle status as availability may vary by region. Ensure the ordering part number matches the exact logical series and package type required for your design specifications.

Selection Notes

Select this component when an octal flip-flop solution is required with low-voltage compatibility down to 2 V. The 74VHC series offers speed comparable to 74HC but with CMOS input/output characteristics. Consider the SOP-20 package constraints for PCB layout. Verify that the 17.1 ns propagation delay meets the timing requirements of your specific application frequency.

Part Context

This component is part of the 74VHC high-speed CMOS logic family produced by onsemi. It serves as a digital storage element within the broader 74-series logic ecosystem. The 74VHC273SJ provides a compact solution for managing multiple data bits simultaneously. It complements other logic devices such as gates and decoders in complex digital circuit designs.

Replacement Considerations

Cross-reference with MM74HCT273SJ or MM74HC273MTCX for alternative packages or series variations. Ensure voltage level compatibility if substituting with HCT series devices which require 5 V logic levels. Verify pinout consistency between SOP-20 variants before implementation.
