SN74HC109NSR

Flip Flops Overview

The SN74HC109NSR is a dual positive-edge-triggered JK flip-flop from the Texas Instruments 74HC logic family. It operates within a supply voltage range of 2 V to 6 V and features CMOS inputs compatible with LVTL standards. The device provides both inverting and non-inverting outputs, housed in a 16-pin SOIC surface-mount package. Key electrical specifications include a maximum propagation delay of 175 ns at 2 V and output drive currents of ±4 mA. It supports set and reset functions and is designed for industrial temperature ranges.

Flip Flops Feature Summary

• Dual independent positive-edge-triggered JK flip-flops integrated into a single package
• Provides complementary inverting and non-inverting outputs for flexible signal routing
• CMOS input structure ensures compatibility with low-voltage TTL logic levels
• Integrated asynchronous set and reset control capabilities

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction and implementation
• Frequency division and counting applications
• General-purpose digital state storage systems

Flip Flops Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm the specific package variant matches the design footprint, as the 'N' designation typically indicates a standard SOIC body width. Ensure the component meets the necessary RoHS compliance standards for the target market regulations before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual JK flip-flop configuration is required within space-constrained surface-mount designs. The HC series offers higher speed performance compared to legacy LS variants while maintaining standard CMOS power consumption characteristics. Consider the 2 V to 6 V operating range to ensure compatibility with the system's primary logic voltage domain without requiring additional level shifting components.

Flip Flops Part Context

This part belongs to the widely adopted 74HC109 family of dual JK flip-flops. It serves as a fundamental building block in synchronous digital logic design. The SN74HC109NSR specifically denotes the surface-mount reel version manufactured by Texas Instruments, distinguishing it from through-hole or alternative vendor equivalents within the same logical specification framework.

Flip Flops Replacement Considerations

CD74HC109M96 is a documented substitute offering similar functionality in an SOIC-16 package.
