SN74AHC74NS

Flip Flops Overview

The SN74AHC74NS is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' AHC logic family. It features CMOS technology with independent clear and preset inputs for each flip-flop. The device operates within a supply voltage range of 2 V to 5.5 V, ensuring compatibility with various digital systems. It utilizes a 14-pin Small Outline (NS) package designed for surface-mount applications. The component supports high-speed data transfer with low power consumption characteristics typical of the AHC series.

Flip Flops Feature Summary

• Dual configuration containing two independent positive-edge-triggered D-type flip-flops
• Integrated asynchronous clear and preset control inputs for direct state management
• CMOS construction enabling operation across a wide 2 V to 5.5 V supply voltage range

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital communication interfaces
• General-purpose storage elements in microprocessor-based systems

Flip Flops Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's current datasheet to confirm the package type and pinout configuration. Ensure the ordering part number matches the exact revision required for your design. Cross-reference the RoHS compliance status and environmental declarations with official documentation before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when dual independent storage with direct clear and preset controls is required in a compact surface-mount form factor. The AHC series offers improved speed and lower power compared to legacy HC logic. Verify that the operating voltage range aligns with the system's power supply rails and that the package dimensions fit the PCB layout constraints.

Flip Flops Part Context

This component belongs to the SNx4AHC74 family of dual D-type flip-flops. It shares functional similarities with other members like the SN74AHC74N but differs in packaging. The NS suffix typically denotes a Small Outline package variant. It serves as a fundamental building block for sequential logic designs requiring reliable data retention and controlled state transitions.
