SN74AC74NSR

Flip Flops Overview

The SN74AC74NSR is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' 74AC logic series. It features set and reset functions with CMOS outputs in a 14-SOIC package. The device operates on a supply voltage range of 2 V to 6 V, supporting a maximum clock frequency of 160 MHz. Key electrical parameters include a propagation delay of 10 ns at 5 V with 50 pF load, output currents of ±24 mA, and static current of 2 µA. It functions within an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent set and reset controls
• High-speed operation with 160 MHz clock frequency capability
• Strong push-pull CMOS outputs providing ±24 mA drive current

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction for digital signal processing
• General-purpose storage elements in microprocessor-based systems

Flip Flops Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-14 surface-mount package variant rather than the PDIP through-hole version. Confirm RoHS3 compliance status as indicated in official documentation. Ensure the ordering part number matches the required reel or cut-tape packaging format specified by the manufacturer's standard distribution channels.

Flip Flops Selection Notes

Select this component when high-speed edge-triggered storage is required within a wide voltage range. The AC series offers superior speed compared to standard 74LS logic while maintaining CMOS low power characteristics. Consider the 14-SOIC package dimensions for PCB layout constraints and thermal management requirements during integration.

Flip Flops Part Context

This device belongs to the SN74AC74 family, which includes variants such as SN74AC74N (PDIP) and SN74AC74PWR (TSSOP). All variants share identical logical functionality but differ in physical packaging and mounting style. The NSR suffix specifically denotes the small-outline integrated circuit form factor suitable for automated surface-mount assembly processes.
