CD74AC112M

Overview

The CD74AC112M is a dual J-K negative-edge-triggered flip-flop manufactured by Harris Corporation. It features independent clear and preset inputs for direct control of the output state. The device operates within a supply voltage range of 1.5V to 5.5V, providing balanced noise immunity at 30% of the supply voltage. It utilizes a 16-SOIC surface-mount package and supports an operating temperature range from -55°C to 125°C.

Feature Summary

• Dual J-K configuration with negative-edge triggering
• Independent active-low clear and preset inputs
• Balanced noise immunity across wide voltage range

Applications

• Digital data storage circuits
• Frequency division networks
• Shift register construction

Procurement Notes

Verify component authenticity due to manufacturer discontinuation. Confirm RoHS compliance status as original specifications may not meet current environmental standards. Validate package integrity and pin alignment against the 16-SOIC footprint requirements before integration into final assemblies.

Selection Notes

Select this component for applications requiring dual J-K functionality with asynchronous control. Ensure the 1.5V to 5.5V operating range aligns with system power rails. Consider the -55°C to 125°C temperature rating for industrial or automotive environments where standard commercial grades are insufficient.

Part Context

This part belongs to the AC logic family, offering speed comparable to bipolar devices with CMOS low power consumption. It is functionally similar to other dual J-K flip-flops but distinguished by its specific Harris Corporation manufacturing origin and extended voltage operation capabilities.

Replacement Considerations

Public confirmed substitute part numbers: SN74AC112DR, SN74ACT112N.
