• Bus holding applications
• Interface between microprocessors and peripheral devices

Latches Procurement Notes

This component is officially discontinued and no longer manufactured by Nexperia. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Substitution with equivalent active parts from the same logic family is recommended for new designs to ensure long-term supply stability.

Latches Selection Notes

Select this part only for legacy system maintenance or repair where original equipment manufacturer specifications must be strictly maintained. For new product development, alternative active components within the 74HCT series should be evaluated to avoid obsolescence risks associated with discontinued manufacturing runs.

Latches Part Context

The 74HCT373 belongs to the 74HCT logic family, which bridges HC and HCT technologies. This specific variant includes tri-state outputs, distinguishing it from non-tri-state counterparts. The DB suffix indicates the SSOP package type, while the 118 code denotes tape-and-reel packaging configuration.

Latches Replacement Considerations

Official substitutes include the 74HCT373PW,118. Verify pinout compatibility and electrical characteristics before implementation.
