Flip Flops Procurement Notes

Verify the manufacturer designation carefully, as the SN74LS107 prefix is historically associated with Texas Instruments. Confirm that onsemi explicitly lists this specific part number in their official documentation or ordering guides. Ensure the datasheet matches the required pinout and electrical characteristics for your design integration.

Flip Flops Selection Notes

Select this component when a dual J-K flip-flop with negative edge triggering is required in surface-mount applications. The LS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Verify compatibility with existing TTL input levels and ensure the SOIC-14 footprint fits the PCB layout constraints.

Flip Flops Part Context

This component belongs to the SN74LS107 family of dual J-K flip-flops. While the 'SN' prefix typically denotes Texas Instruments products, onsemi manufactures equivalent devices under similar naming conventions. It serves as a fundamental building block for sequential logic designs requiring bistable memory elements.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS107N (Texas Instruments PDIP version) and the SN74LS107ANSR (Texas Instruments SOIC version). Cross-reference with other manufacturers offering LS-series dual J-K flip-flops in SOIC-14 packages if sourcing availability is limited.
