Flip Flops Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of qualified substitutes such as MC74ACT374DWG or Texas Instruments equivalents like CD74ACT374M96. Ensure that replacement components match the required 20-SOIC package dimensions and electrical specifications to maintain system compatibility without redesign.

Flip Flops Selection Notes

Select this component when designing systems requiring eight-bit parallel data latching with tri-state output control. Consider the ACT series characteristics for TTL-compatible inputs and moderate speed performance. Evaluate the 20-SOIC footprint against PCB space constraints. Verify that the 4.5V to 5.5V operating range aligns with the target power supply infrastructure and thermal environment requirements.

Flip Flops Part Context
