Flip Flops Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the TSSOP56 footprint matches your PCB design constraints. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring wide 20-bit data latching at high frequencies. The ABT series offers superior speed compared to standard logic families. Ensure power supply decoupling is adequate for the 5.5 V maximum rating and verify thermal dissipation requirements for the TSSOP56 package under continuous operation.

Flip Flops Part Context

This part belongs to the 74ABT family of high-speed BICMOS logic devices. It serves as a successor to older 74F and 74S series technologies, offering improved switching speeds while maintaining compatible pinouts. The 16821 variant specifically addresses applications needing extensive parallel data handling within compact integrated circuit form factors.

Flip Flops Replacement Considerations

Check for direct equivalents such as the 74ABT16821ADG or other 20-bit ABT flip-flops from NXP/Nexperia. Verify that any substitute maintains identical 3-state output characteristics and operating voltage ranges.
