Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor has been acquired by ON Semiconductor. Ensure the part number suffix matches the required package type and lead-free status. Confirm RoHS compliance documentation is available from the supplier. Check for obsolescence notices or lifecycle status changes due to corporate restructuring. Validate that the distributor is an authorized source for genuine components.

Selection Notes

Select this component when an octal D-type flip-flop with 5V tolerance is required in a 20-pin SOIC package. It is suitable for designs needing high-speed data latching with low power consumption. Compare against similar LCX series parts if different pinouts or electrical characteristics are needed. Ensure the operating voltage range aligns with the system's 2.0V to 3.6V supply rails.

Part Context

The 74LCX374SJX belongs to the 74LCX logic family, which is designed for low voltage and low power applications. This specific part is an octal D-type flip-flop, providing eight independent D-type flip-flops with common clock and output enable controls. It is widely used in portable and battery-powered devices where power efficiency and speed are critical.

Replacement Considerations

The 74LCX374SJ_NL is a comparable part from Fairchild/ON Semiconductor with similar specifications. Verify pinout compatibility and electrical parameters before substitution. Other equivalents may exist within the 74LCX family, but package and timing differences must be checked.
