SN74F112NG4

Flip Flops Overview

The SN74F112NG4 is a dual JK-type flip-flop integrated circuit manufactured by Texas Instruments, belonging to the high-speed 74F logic series. It features negative-edge triggering and includes independent preset and clear inputs for direct control of output states. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 130 MHz. Propagation delay is specified at 6.5 ns under standard load conditions. It utilizes a 16-pin DIP package designed for through-hole mounting, suitable for industrial temperature ranges from 0°C to +70°C.

Flip Flops Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm package integrity and pin configuration match the 16-DIP specification. Ensure storage conditions comply with moisture sensitivity level requirements. Cross-reference ordering information with official Texas Instruments documentation to avoid counterfeit risks.

Flip Flops Selection Notes

Select this component when high switching speed is critical compared to standard 74-series logic. The F-series offers faster propagation delays than HC or LS variants but requires careful power supply decoupling due to higher current consumption. Ensure system voltage remains strictly within the 4.5V to 5.5V range to maintain timing specifications.

Flip Flops Part Context

This part belongs to the SN74F family, known for high-speed performance in TTL-compatible logic applications. It serves as a fundamental building block for sequential circuits requiring precise timing control. The 'G4' suffix indicates compliance with specific environmental standards, such as RoHS directives, while maintaining functional equivalence to the base SN74F112 model.

Flip Flops FAQ

What is the trigger type of the SN74F112NG4?

The device uses negative-edge triggering, meaning state changes occur on the falling edge of the clock signal.

Does the SN74F112NG4 have asynchronous control inputs?

Yes, it includes independent active-low preset and clear inputs that override the clock and J/K inputs to set or reset the output immediately.
