Multivibrators Procurement Notes

Verify component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm availability of direct substitutes such as the CD74HC123M96 variant. Ensure compliance with RoHS3 specifications and check for any product change notices regarding manufacturing updates or discontinuation schedules.

Multivibrators Selection Notes

Select this component when dual monostable functionality is required within the 74HC family constraints. Verify that the 16-SOIC package dimensions fit the design layout. Confirm that the absence of Schmitt trigger inputs aligns with input signal requirements. Check operating voltage compatibility against the 2 V to 6 V specification range.

Multivibrators Part Context

This part belongs to the broader 74HC123 family of dual monostable multivibrators. It shares functional characteristics with other variants like the CD74HC123MT but differs in packaging and tube quantity. The ME4 suffix indicates specific manufacturing and environmental compliance attributes within the Texas Instruments portfolio.

Multivibrators Replacement Considerations

The CD74HC123M96 is listed as a direct substitute. Verify pinout and electrical parameter equivalence before integration.
