SN74ACT74NSR

Flip Flops Overview

The SN74ACT74NSR is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74ACT series. It features TTL-compatible inputs and CMOS outputs, housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 11 ns, with low-level output current capability of 24 mA and high-level output current of -24 mA. It supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flop architecture
• TTL-compatible input logic levels
• CMOS output structure for low power consumption
• Standard non-inverting and inverting outputs

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Timing and control circuit synchronization

Flip Flops Procurement Notes

Verify the specific suffix NSR indicates the SOIC-14 surface mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the specified 4.5 V to 5.5 V supply voltage constraints and thermal requirements for the industrial temperature range.

Flip Flops Selection Notes

Select this component when TTL interface compatibility is required alongside CMOS output drive capabilities. The ACT series offers improved speed over standard LS logic while maintaining pin-out compatibility. Verify that the SOIC-14 footprint matches the PCB layout and that the 11 ns propagation delay meets system timing requirements.

Flip Flops Part Context

This part belongs to the SN74ACT family, which combines the speed of AS logic with the low power of AC logic. It serves as a direct replacement for older TTL flip-flops in modern designs requiring higher performance and lower power dissipation. The dual configuration allows efficient use of board space for multi-bit storage applications.
