Flip Flops Procurement Notes

Verify component status carefully as this part number is listed as obsolete and no longer manufactured by onsemi. Sourcing may be limited to distributor surplus or secondary market channels. Confirm authenticity and condition through authorized distributors. Check for available substitute part numbers such as MC74LCX374DTR2G if new production units are required for design continuity.

Flip Flops Selection Notes

Select this component only for legacy system maintenance or repair where original part matching is critical. For new designs, consider active substitutes within the 74LCX374 family that offer identical pinouts and electrical characteristics. Evaluate availability constraints and potential long-term supply risks associated with obsolete logic devices before finalizing specifications.

Flip Flops Part Context

This device belongs to the 74LCX374 family of octal D-type flip-flops with tri-state outputs. It is designed for low-voltage CMOS applications requiring high-speed performance. The LCX series offers compatibility with standard TTL interfaces while operating at lower voltages. This specific MELG variant utilizes a 20-SOIC package format suitable for surface-mount assembly.

Flip Flops Replacement Considerations

MC74LCX374DTR2G is confirmed as an available substitute part number. Verify pinout compatibility and electrical parameters before substitution. Ensure packaging differences do not impact board layout requirements.
