Flip Flops Procurement Notes

Verify the specific suffix 'FR1' against the official onsemi datasheet to confirm tape-and-reel packaging specifications and pinout compatibility. Ensure that the selected variant meets the required thermal and electrical standards for the intended application environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status prior to procurement.

Flip Flops Selection Notes

Select this component when a dual D-flip-flop with independent set and reset functions is required in a surface-mount design. Consider the 14-SOIC package size and the 2.0V to 6.0V operating range for compatibility with existing power rails. Evaluate the 17ns propagation delay and 35MHz speed against the system timing requirements to ensure adequate performance margins.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. It is functionally equivalent to other industry-standard dual D-flip-flops but offers specific packaging and performance characteristics defined by onsemi. The device is designed for use in general-purpose digital logic applications requiring reliable state retention and fast switching capabilities.

Flip Flops Replacement Considerations

Direct substitutes include MC74HC74A and MC74HC74ADG from onsemi, which share identical pinouts and logical functionality. Verify that alternative packages or suffixes maintain the same electrical parameters and operating temperature ranges before substitution.
