M74HC76B1R

Flip Flops Overview

The M74HC76B1R is a dual JK-type flip-flop integrated circuit manufactured by STMicroelectronics. It features two independent flip-flops with clock, preset, and clear inputs in a 16-DIP package. The device operates on a single supply voltage ranging from 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 38 ns at 4.5 V with 150 pF load, static current of 4 µA, and output drive currents of 6 mA for both high and low states. It supports a wide operating temperature range from -55°C to 125°C.

Flip Flops Feature Summary

• Dual JK flip-flop architecture with independent clock, preset, and clear control inputs
• Wide single-supply voltage operation compatible with standard logic families
• High noise immunity and robust performance across extended industrial temperature ranges

Flip Flops Applications

• Digital data storage and register circuits
• Frequency division and counter applications
• State machine implementation in sequential logic systems

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific manufacturing date codes against project requirements. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage to the CMOS input structures.

Flip Flops Selection Notes

Select this component when dual JK functionality is required within a HC series logic family. Consider the 16-DIP package for through-hole prototyping or legacy board designs. Evaluate the 2 V to 6 V operating range against system power constraints and verify that the 38 ns propagation delay meets timing requirements for the target clock frequencies.

Flip Flops Part Context

This part belongs to the M74HC74/M74HC76 series of dual JK flip-flops from STMicroelectronics. It complements other logic ICs like the M74HC4066 analog switch and M74HC257 multiplexer within the same HC technology node. The device provides essential sequential logic capabilities alongside combinational logic components in mixed-signal digital designs.

Flip Flops Replacement Considerations

Direct substitutes include equivalent JK flip-flop ICs from other manufacturers such as SN74HC76N from Texas Instruments. Verify pin compatibility and electrical specifications before substitution. Alternative packages may require adapter solutions if surface-mount variants are preferred over the original DIP format.
