CD74HC112M

Overview

The CD74HC112M is a dual JK flip-flop integrated circuit manufactured by Harris Corporation, belonging to the 74HC series. It features two independent 1-bit flip-flops with negative edge triggering and active-low preset and clear inputs. The device operates on a supply voltage range of 2V to 6V and supports a maximum frequency of 35MHz. It is housed in a 16-SOIC surface-mount package with dimensions of 0.154 inches (3.90mm) width. The component functions within an operating temperature range of -55°C to 125°C.

Feature Summary

• Dual JK flip-flop configuration with negative edge triggering for precise timing control
• Active-low asynchronous preset and clear inputs for immediate state initialization
• CMOS technology ensuring low power consumption and high noise immunity

Applications

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

Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets were acquired. Confirm RoHS compliance status, as older Harris parts may not meet current environmental standards. Check for lead-free plating requirements if integrating into modern assemblies. Ensure the SOIC-16 footprint matches PCB design constraints. Validate that the 2V-6V supply range aligns with system power rails.

Selection Notes

Select this component when dual independent JK flip-flops are required in a compact surface-mount form factor. The HC series offers compatibility with standard CMOS logic levels. Consider the 35MHz speed limit for high-frequency applications. The wide operating temperature range suits industrial environments. Verify pinout compatibility if replacing legacy through-hole DIP versions.

Part Context

This part belongs to the Harris 74HC logic family, known for high-speed CMOS operation. Harris Corporation was a significant semiconductor provider before its acquisition by Renesas Electronics. The CD74HC prefix indicates commercial grade temperature range and HC speed/power characteristics. This specific model represents a discrete logic solution for sequential circuit design.

Replacement Considerations

CD74HC112N (DIP version), SN74HC112N (Texas Instruments equivalent). Verify pin compatibility and electrical specifications before substitution.
