SN74HC109N

Flip Flops Overview

The SN74HC109N is a dual JK flip-flop integrated circuit from Texas Instruments, belonging to the HC logic series. It features single-ended inputs and differential outputs with both inverting and non-inverting polarities. The device supports positive edge triggering and includes set/reset functionality. Packaged in a 16-pin PDIP for through-hole mounting, it operates within a supply voltage range of 2 V to 6 V. The component functions reliably across an extended temperature range of -40°C to +85°C, with a maximum propagation delay of 175 ns at 2 V.

Flip Flops Procurement Notes

Verify the specific package type and pin count against project requirements before procurement. Confirm that the through-hole PDIP-16 form factor aligns with the PCB layout design. Ensure the operating voltage range and temperature specifications meet the environmental constraints of the target application. Cross-reference the manufacturer part number to avoid confusion with similar logic families or variants.

Flip Flops Selection Notes

Select this component when a dual JK flip-flop with differential outputs is required for through-hole assembly. The HC logic family offers compatibility with standard CMOS interfaces while supporting a wide supply voltage range. Consider the propagation delay characteristics for timing-sensitive designs. Verify that the single-ended input requirement matches the driving source interface capabilities.

Flip Flops Part Context

This device is part of the broader Texas Instruments SN74xx logic family, specifically designed for general-purpose digital applications. The HC series provides high-speed operation with low power consumption compared to earlier logic standards. As a JK flip-flop, it serves as a fundamental building block for sequential logic circuits, enabling complex state management in digital systems.

Flip Flops Replacement Considerations

Compatible substitutes include other dual JK flip-flops from the same logic family, such as the SN74HC109NSR in SOIC-16 packaging. Alternative manufacturers may offer equivalent parts, but electrical parameters and pin configurations must be verified for direct replacement without circuit modification.
