• Edge-triggered storage register design for reliable data retention

Flip Flops Applications

• General-purpose 6-bit storage registers
• Parallel-to-serial conversion circuits
• Data acquisition systems requiring edge-triggered memory elements

Flip Flops Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 package variant when sourcing. Confirm RoHS compliance status as some listings indicate non-compliance while others may differ based on revision. Ensure the operating temperature range of -40°C to +85°C aligns with system requirements. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Flip Flops Selection Notes

Select this component for applications requiring moderate speed logic operations within a 2V to 6V supply range. The 6ns propagation delay suits general digital timing needs but may not meet ultra-high-frequency requirements exceeding 125MHz. Consider the SOIC-16 package constraints for PCB layout. Compare against AC or ACT series variants if different voltage thresholds or drive strengths are necessary for the specific interface.

Flip Flops Part Context

This part belongs to the 74AC series of high-speed CMOS logic devices produced by onsemi. It is functionally compatible with standard 74AC logic families, ensuring interoperability with other components from the same lineage. The device represents a standard solution for basic sequential logic functions in consumer and industrial electronics where cost-effective, reliable storage is required.

Flip Flops Replacement Considerations

Direct substitutes include the MC74ACT174D for 5V-only applications with TTL-compatible inputs. Other hex D flip-flops from the 74HC or 74HCT series may serve as alternatives if speed requirements are lower. Verify pinout compatibility and voltage level matching before swapping.
