Flip Flops Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS3 compliance requirements if mandated by project standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing 5V CMOS logic systems requiring dual D-type storage elements. The ACT series offers performance comparable to LS-TTL while maintaining CMOS power advantages. Consider the 14-SOIC package dimensions for PCB layout constraints and verify that the operating temperature range of -40°C to 85°C aligns with environmental conditions.

Flip Flops Part Context

This device is part of the broader 74ACT family of high-speed CMOS logic integrated circuits produced by onsemi. The 74ACT74 specifically provides two independent D-type flip-flops within a single package, serving as a fundamental building block for sequential logic design in digital electronics applications requiring reliable state retention and timing control.
