Procurement Notes

Verify the exact suffix SJX corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the operating temperature range meets your environmental specifications before finalizing orders. Ensure compatibility with your PCB footprint design regarding pin pitch and thermal requirements. Cross-reference the manufacturer's latest datasheet revision to confirm any updates to electrical characteristics or mechanical dimensions.

Selection Notes

Choose this component when designing systems that require dual independent flip-flops with set/reset functionality in a small form factor. It is suitable for applications demanding low voltage operation between 2.0V and 3.6V. Consider its Schmitt-trigger inputs if the signal environment has significant noise. Evaluate the trade-off between speed and power consumption based on your system's timing constraints and battery life requirements.

Part Context

This part belongs to the 74LCX series of high-speed CMOS logic devices from onsemi. The LCX family is known for its compatibility with both 3.3V and 5V systems through level shifting capabilities. As a JK flip-flop variant, it provides versatile state management compared to simpler D-type counterparts. The SJX suffix indicates a specific commercial grade temperature range and packaging style distinct from industrial or automotive variants.

Replacement Considerations

Direct substitutes include other 74LCX112 variants from different manufacturers offering identical pinouts and logical functions. Verify that alternative sources maintain the same voltage tolerance and switching speed specifications. Check for equivalent packaging options if your manufacturing process requires different reel sizes or lead-free compliance standards.
