MM74C76MX

Flip Flops Overview

The MM74C76MX is a dual J-K flip-flop integrated circuit manufactured by Fairchild Semiconductor, now part of onsemi. It features two independent negative-edge triggered flip-flops in a single 16-SOIC package. The device operates with a supply voltage range of 3V to 15V and supports a maximum clock frequency of 11 MHz. Key electrical specifications include a maximum propagation delay of 130ns at 10V with a 50pF load. It utilizes complementary MOS (CMOS) technology for low power consumption.

Flip Flops Feature Summary

• Dual J-K flip-flop configuration with negative edge triggering
• Wide operating supply voltage range from 3V to 15V
• Complementary MOS (CMOS) construction for enhanced performance

Flip Flops Applications

• Digital logic circuits requiring state storage
• Frequency division and counting applications
• Data register implementations in embedded systems

Flip Flops Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor's logic products are now managed under onsemi. Confirm the specific suffix 'MX' corresponds to the 16-SOIC package variant. Ensure compliance with RoHS requirements if applicable, as some listings indicate non-compliance. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Flip Flops Selection Notes

Select this component when a dual J-K flip-flop with wide voltage tolerance is required. The 11 MHz clock limit suits moderate-speed digital designs. Consider the 16-SOIC footprint for PCB layout constraints. Compare propagation delays against system timing budgets to ensure signal integrity. Verify input logic levels match the chosen supply voltage within the 3V-15V range.

Flip Flops Part Context

This component belongs to the standard 74C series of CMOS logic devices, known for broader voltage operation compared to earlier TTL or HC families. The MM74C76 specifically provides dual J-K functionality, offering versatile toggling and set/reset capabilities. It serves as a fundamental building block for sequential logic circuits in industrial and consumer electronics.

Flip Flops Replacement Considerations

Direct substitutes include other dual J-K flip-flops in SOIC packages such as the CD4027B or MC14576B. Verify pin compatibility and electrical characteristics like propagation delay and supply voltage ranges before substitution. Ensure the replacement device meets the same negative-edge trigger requirement.
