Procurement Notes

Verify the specific suffix '653' indicates tape-and-reel packaging when ordering. Confirm that the 14-SOIC footprint matches the target PCB design. Ensure the supply voltage requirements align with the 2V to 6V operational range specified in the datasheet. Cross-reference the manufacturer part number with official Nexperia documentation to confirm current production status and availability.

Selection Notes

Select this component for designs requiring dual JK flip-flops in a compact surface-mount format. The HCT technology ensures TTL-compatible input levels while offering CMOS power efficiency. Consider the 36ns propagation delay at 4.5V for timing constraints. The SOIC-14 package provides a balance between pin count and board space efficiency for moderate complexity digital systems.

Part Context

This device belongs to the 74HCT series, which combines the speed of high-speed CMOS with TTL-compatible inputs. The base product number is 74HCT107. The 'D' suffix denotes the SOIC-14 package type, while '653' specifies the reel packaging configuration. It serves as a fundamental building block for sequential logic in digital electronics.

Replacement Considerations

Compatible substitutes include other dual JK flip-flops in the 74HCT family such as the 74HCT107PW. Verify pin compatibility and electrical specifications before substitution. Alternative packages like TSSOP may require adapter solutions if space constraints differ.
