Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-14 surface mount package configuration. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supply voltage remains strictly within the 4.5 V to 5.5 V range to maintain signal integrity. Check for any obsolescence notices or lifecycle status changes before finalizing procurement plans.

Selection Notes

Select this component when TTL-compatible logic levels are required alongside CMOS performance benefits. The HCT series ensures compatibility with standard TTL inputs while offering lower power consumption than traditional LS logic. Consider the SOIC-14 package for space-constrained surface-mount designs requiring robust thermal performance across extended temperature ranges.

Part Context

This part belongs to the CD74HCT74 family of dual D-type flip-flops. It shares functional similarities with other HCT series devices but is distinguished by its specific pinout and package type. The family is designed to bridge the gap between legacy TTL systems and modern CMOS technologies, providing reliable data storage capabilities in compact integrated circuit formats.
