SN74HC109NG4

Flip Flops Overview

The SN74HC109NG4 is a dual J-K flip-flop from the Texas Instruments HC logic family, housed in a 16-pin PDIP package. It features positive edge triggering with set and reset capabilities. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 175 ns at 2 V with a 50 pF load, and output currents of -4 mA (high) and 4 mA (low). It supports CMOS and LVTTL inputs, providing both inverting and non-inverting outputs across its two internal circuits.

Flip Flops Feature Summary

• Dual J-K flip-flops with positive edge triggering
• Integrated set and reset control functions
• CMOS compatible input structure with LVTTL support
• Simultaneous inverting and non-inverting outputs

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Frequency division circuits
• Event counting applications

Flip Flops Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific RoHS-compliant variant and manufacturing code required for your design. Confirm the physical package matches the 16-pin PDIP specification rather than surface-mount alternatives like SOIC or TSSOP. Ensure the component meets the required temperature range specifications for your intended operational environment before finalizing procurement.

Flip Flops Selection Notes

Select this component when a dual J-K flip-flop with separate set and reset lines is required in a through-hole design. It is suitable for systems operating between 2 V and 6 V where moderate speed is acceptable. Consider alternative packages if surface-mount technology is preferred, or different logic families if faster switching speeds are necessary for high-frequency applications.

Flip Flops Part Context

This part belongs to the standard 74HC series of CMOS digital logic integrated circuits. It provides a widely used solution for sequential logic operations in general-purpose digital systems. The HC series is known for compatibility with various logic families and offers robust performance across a wide voltage range, making it a staple for educational and industrial digital circuit designs.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74HC109N and SN74HC109DR. Verify that any replacement maintains the same PDIP-16 package and logical functionality. Ensure the substitute part supports the required voltage and temperature ranges.
