Flip Flops Procurement Notes

Verify the specific suffix 'DTR2G' against procurement requirements, as it indicates tape-and-reel packaging and RoHS compliance. Confirm that the 20-TSSOP package dimensions align with PCB footprint constraints. Ensure the 4.5V to 5.5V supply voltage range matches the target system's power rails. Check for any recent Product Change Notifications (PCN) regarding manufacturing site or material changes.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required in a 5V logic environment. The ACT series offers faster switching speeds compared to standard AC or HC families while maintaining CMOS compatibility. Consider the 20-TSSOP package for surface-mount applications where space efficiency is critical. Evaluate the 10ns propagation delay against system timing requirements to ensure signal integrity.

Flip Flops Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices from onsemi. It is functionally compatible with other 74ACT octal flip-flops but distinguished by its specific package and trailing suffix indicating reel packaging. It serves as a core building block for sequential logic circuits in industrial and consumer electronics.

Flip Flops Replacement Considerations

SN74ACT374PWR from Texas Instruments is a documented alternative. Verify pinout compatibility and electrical specifications before substitution.
