SN74HC109NE4

Flip Flops Overview

The SN74HC109NE4 is a dual JK-type flip-flop from the Texas Instruments HC logic series, housed in a 16-pin PDIP package. It features single-ended inputs and complementary outputs with rise-edge triggering. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. Maximum propagation delay is specified at 175 ns under 2 V conditions with 50 pF load.

Flip Flops Feature Summary

• Contains two independent JK flip-flops per package
• Provides both inverting and non-inverting output polarities
• Includes dedicated set and reset control functions

Flip Flops Applications

• Digital data storage circuits
• Shift register configurations
• Frequency division applications

Flip Flops Procurement Notes

Verify that the ordering suffix NE4 confirms the lead-free and RoHS-compliant status as documented by Texas Instruments. Ensure the procurement channel provides official datasheets matching this specific part number to confirm the PDIP-16 through-hole package type and active lifecycle status.

Flip Flops Selection Notes

Select this component when a dual JK flip-flop with complementary outputs is required for through-hole PCB designs. The HC series offers CMOS compatibility suitable for low-power applications. Verify that the 2 V to 6 V supply range aligns with the system requirements and that the PDIP-16 package fits the available board space.

Flip Flops Part Context

This part belongs to the standard 74HC logic family, widely used for general-purpose digital logic. The SN74HC109 variant specifically implements JK functionality with edge-triggering. The E4 suffix indicates environmental compliance, distinguishing it from standard commercial variants while maintaining identical electrical performance specifications.

Flip Flops Replacement Considerations

Public confirmed substitutes include SN74HC109N and SN74HC109NSR.
