CD74AC74M

Overview

The CD74AC74M is a dual D-type positive edge-triggered flip-flop manufactured by Harris Corporation using ADVANCED CMOS technology. It features asynchronous Clear and Set inputs along with complementary Q and Q outputs. The component is housed in a 14-SOIC surface-mount package, designed for operation within a supply voltage range of 2V to 6V and an operating temperature range of -55°C to 125°C.

Feature Summary

• Dual D-type positive edge-triggered flip-flops
• Asynchronous Clear and Set inputs
• Complementary Q and Q outputs
• ADVANCED CMOS technology

Applications

• Digital data storage circuits
• Shift register construction
• Frequency division applications
• State machine implementation

Procurement Notes

Verify the specific manufacturer source, as Harris Corporation's logic assets were acquired by other entities. Confirm RoHS compliance status, as older Harris variants may not meet current environmental standards. Ensure the SOIC-14 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when dual independent D-type latching is required in a compact surface-mount form factor. The ADVANCED CMOS process offers high-speed performance suitable for digital systems. Consider the 2V to 6V supply range compatibility with existing system voltages during circuit design.

Part Context

This part belongs to the Harris CD74AC series of logic devices. It serves as a fundamental building block for sequential logic circuits. The 'M' suffix indicates the SOIC surface-mount package variant, distinguishing it from through-hole DIP versions like the CD74AC74E.

Replacement Considerations

Compatible substitutes include the MC74AC74M from ON Semiconductor, which shares identical pinout and logical functionality. Verify that alternative sources maintain the same ADVANCED CMOS specifications and package dimensions for direct replacement.
