SN74F112NE4

Flip Flops Overview

The SN74F112NE4 is a dual JK-type flip-flop from the Texas Instruments 74F series, housed in a 16-pin PDIP package. It operates on a supply voltage of 4.5V to 5.5V with a maximum propagation delay of 6.5ns at 5V and 50pF load. The device features negative-edge triggering, set and reset functions, and outputs in both complementary forms. It supports a clock frequency of 130MHz and draws a static current of 19mA. Operating temperatures range from 0°C to +70°C.

Flip Flops Feature Summary

• Dual JK flip-flops with negative-edge triggering for precise timing control
• Integrated set and reset inputs for direct state management
• Complementary outputs providing both true and inverted logic signals

Flip Flops Applications

• High-speed digital data storage circuits
• Frequency division and counting applications
• Shift register construction

Flip Flops Procurement Notes

Verify the 'E4' suffix indicates lead-free composition and compliance with specific environmental standards as defined by Texas Instruments. Confirm that the PDIP-16 package matches your PCB footprint requirements. Ensure the 70°C operating temperature limit aligns with your system's thermal environment before finalizing procurement.

Flip Flops Selection Notes

Select this component when high switching speed is critical, as the F series offers faster performance than standard TTL or HC variants. Consider the higher power consumption compared to CMOS alternatives. Verify that the 16-pin DIP package fits your assembly process constraints. This part is suitable for designs requiring dedicated set and reset capabilities alongside fast clocking.

Flip Flops Part Context
