MM74C76N

Flip Flops Overview

The MM74C76N is a dual J-K flip-flop integrated circuit manufactured by onsemi, belonging to the 74C CMOS logic series. It features two independent circuits within a single package, designed for negative edge triggering. The device operates with a supply voltage range of 3 V to 15 V and supports a maximum clock frequency of 11 MHz. Key electrical parameters include a propagation delay of 300 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It is housed in a 16-pin DIP (0.300 inch) package and functions reliably across an extended temperature range from -55°C to +125°C.

Flip Flops Feature Summary

• Dual J-K flip-flop configuration providing two independent 1-bit storage elements per package
• Negative edge-triggered operation for precise timing control in synchronous digital systems
• Wide operating voltage capability supporting standard 3V to 15V CMOS power supplies
• Extended industrial temperature rating ensuring stability in harsh environmental conditions

Flip Flops Applications

• Binary counter circuits requiring dual-stage data storage
• Shift register implementations utilizing serial-in parallel-out architectures
• Frequency division logic within clock signal processing networks
• State machine design components for sequential logic control systems

Flip Flops Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance status as historical records indicate non-compliance for this specific legacy part number. Request original manufacturer datasheets to validate pinout and electrical specifications against current application requirements. Ensure proper handling procedures are followed due to the component's discontinued status and potential age-related degradation risks.

Flip Flops Selection Notes

Select the MM74C76N when dual J-K functionality is required within a wide voltage environment. Consider its 300 ns propagation delay for applications not demanding high-speed switching. Evaluate the 16-pin DIP package suitability for through-hole mounting constraints. Compare against modern HC or HCT series alternatives if lower power consumption or faster switching speeds are necessary for the target design.

Flip Flops Part Context

This component belongs to the legacy 74C family of CMOS logic devices produced by onsemi. It serves as a fundamental building block for sequential logic designs, offering reliable performance in industrial and commercial applications. The MM74C76N represents a standard solution for dual flip-flop requirements before the widespread adoption of higher-density integration technologies.
