Flip Flops Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for this specific part number. Confirm package integrity upon receipt, ensuring no physical damage to the 16-DIP leads. Check manufacturing date codes against project requirements to ensure component freshness. Validate that the received units match the exact MC74HC112N designation to avoid confusion with similar variants. Maintain proper ESD handling procedures during storage and assembly.

Flip Flops Selection Notes

Select this component when a dual J-K flip-flop with through-hole mounting is required for robust industrial environments. The wide temperature range makes it suitable for harsh conditions exceeding standard commercial limits. Consider the 7.62mm DIP width for PCB layout constraints. Ensure supply voltage remains within the 2V-6V window for optimal performance. Verify that the 35MHz clock limit meets system speed requirements before finalizing the design.

Flip Flops Part Context

This device is part of onsemi's extensive 74HC series, known for high-speed CMOS operation compatible with TTL inputs. The MC74HC112 specifically addresses applications needing dual bistable elements. It complements other logic families by offering improved noise immunity and lower power consumption compared to older transistor-transistor logic counterparts. The DIP packaging facilitates easy prototyping and replacement in legacy systems.

Flip Flops Replacement Considerations

Direct substitutes include SN74HC112N from Texas Instruments, which shares identical logical function and pinout compatibility. Other manufacturers may offer equivalent parts under different numbering schemes but require careful verification of electrical characteristics and package dimensions to ensure seamless integration without circuit modification.
