Flip Flops Procurement Notes

Verify the specific manufacturer source for the SN74LS107ADR, as this part number is primarily associated with NXP Semiconductors rather than Texas Instruments. Confirm that the received component matches the required LS logic family specifications and SOIC-14 package dimensions. Ensure the datasheet provided aligns with the expected electrical characteristics, particularly the 45 MHz clock limit and TTL-compatible input/output levels. Cross-reference the ordering information to confirm the correct suffix and package type are selected.

Flip Flops Selection Notes

Select the SN74LS107ADR when a dual J-K flip-flop with complementary outputs is required for space-constrained designs utilizing surface-mount technology. This component is suitable for applications needing negative edge triggering and asynchronous reset capabilities within standard TTL logic families. Consider the 20 ns propagation delay and 45 MHz maximum frequency for timing-sensitive digital circuits. Ensure the design accommodates the 4.75 V to 5.25 V power supply requirements and the specified thermal operating range.

Flip Flops Part Context

The SN74LS107ADR belongs to the broader category of dual J-K flip-flops used in sequential logic circuits. While the SN74LS107AN variant utilizes a PDIP through-hole package, the ADR suffix indicates a plastic small-outline (SOIC) surface-mount configuration. This component serves as a fundamental building block for state machines and data storage elements in digital systems, offering a compact solution compared to larger through-hole alternatives while maintaining standard LS logic performance characteristics.

Flip Flops Replacement Considerations

The SN74LS107ANSR is a direct equivalent from Texas Instruments featuring the same logic function but in an SOIC-14 package. For alternative sourcing, the SN74LS107AD from NXP Semiconductors provides identical electrical specifications and pinout compatibility.
