MC74HC112ADTG

Flip Flops Overview

The MC74HC112ADTG is a dual J-K flip-flop integrated circuit manufactured by onsemi, belonging to the 74HC logic family. It features two independent negative-edge-triggered JK flip-flops with preset and clear inputs within a single package. The device operates on a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 35 MHz. It utilizes a 16-pin DIP (0.300", 7.62mm) surface-mount or through-hole compatible package. Key electrical parameters include a propagation delay of 21 ns at 6 V with 50 pF load, output current capability of ±5.2 mA, and static current of 4 µA. The component functions reliably across an extended temperature range from -55°C to +125°C.

Flip Flops Feature Summary

• Dual configuration containing two independent JK flip-flops for compact state storage
• Negative-edge triggering mechanism ensures precise timing synchronization
• Integrated asynchronous preset and clear control inputs for immediate state initialization

Flip Flops Applications

• Digital data storage and register circuits
• Frequency division and counter logic design
• State machine implementation in embedded systems

Flip Flops Procurement Notes

Verify RoHS compliance status as documentation indicates potential variations between leaded and lead-free versions. Confirm package type matches the specific suffix requirements for your assembly process. Check manufacturer announcements for end-of-life notices, as this series may be subject to discontinuation. Ensure ordering specifications align with the required operating temperature range and voltage levels.

Flip Flops Selection Notes

Select this component when dual JK functionality is required in a standard HC logic family environment. Consider the 16-pin DIP package for prototyping or legacy board compatibility. Evaluate the 35 MHz speed limit against system clock requirements. Compare against VHC variants if higher switching speeds are necessary for modern high-frequency applications.

Flip Flops Part Context
