Flip Flops Procurement Notes

Verify RoHS compliance status as records indicate non-compliance for this specific part number. Confirm package integrity upon receipt, as PDIP-16 units are susceptible to lead damage during shipping. Ensure sourcing channels provide traceability documentation matching Fairchild Semiconductor manufacturing standards.

Flip Flops Selection Notes

Select this component when dual independent flip-flops with complementary outputs are required in a DIP package. Consider the 74ACT109 if TTL-compatible input thresholds are necessary instead of standard CMOS levels. Verify voltage requirements align with the 2 V to 6 V operating range before integration into the target circuit design.

Flip Flops Part Context

This device belongs to the 74AC family of high-speed CMOS logic components. The AC series offers significantly faster switching speeds compared to legacy 74HC devices while maintaining lower power dissipation than older 74ALS technologies. The 74AC109 specifically addresses applications requiring dual bistable elements within a single integrated circuit package.

Flip Flops Replacement Considerations

The 74ACT109 serves as a functional substitute offering identical pinout and logic behavior but with TTL-compatible input thresholds.
