MM74HC74AM

Flip Flops Overview

The MM74HC74AM is a dual D-type flip-flop from the onsemi HC logic family, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40 °C to +85 °C. The device features independent data, preset, clear, and clock inputs with Q and Q-bar outputs. Key electrical parameters include a propagation delay of 110 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It utilizes advanced silicon-gate CMOS technology for high noise immunity and low power consumption.

Flip Flops Feature Summary

• Dual positive-edge triggered D-type flip-flops with complementary outputs
• Independent asynchronous preset and clear functions active at low level
• High noise immunity and low power consumption via silicon-gate CMOS technology
• Internal input protection against static discharge damage

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• General-purpose storage elements in digital systems
• Timing and control logic applications

Flip Flops Procurement Notes

Verify the specific suffix 'AM' corresponds to the SOIC-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure that the ordering part number matches the exact pinout and electrical specifications required for the target design to avoid compatibility issues with existing PCB layouts.

Flip Flops Selection Notes

Select this component for designs requiring dual D-type storage with complementary outputs in a surface-mount format. It is suitable for applications needing operation across a wide voltage range down to 2 V. Consider the 110 ns propagation delay for timing constraints. Verify that the SOIC-14 footprint aligns with available board space and manufacturing capabilities compared to TSSOP alternatives.

Flip Flops Part Context

This device belongs to the MM74HC74A series, representing dual D-type flip-flops within the broader 74HC logic family. The HC series is known for high-speed CMOS operation compatible with standard TTL logic levels. Variants such as MM74HC74AMTC offer similar functionality in different packages like TSSOP-14, while MM74HC74AMX provides tape-and-reel packaging options for automated assembly processes.

Flip Flops Replacement Considerations

• MM74HC74AMTC (TSSOP-14 package)
• MM74HC74AMX (SOIC-14 tape and reel)
