SN74ACT74NS

Flip Flops Overview

The SN74ACT74NS is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74ACT series. It features CMOS outputs and TTL-compatible inputs, housed in a 14-pin SOIC package with surface-mount installation. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, a high-level output current of -24 mA, and a low-level output current of 24 mA. It supports an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Integrates two independent D-type flip-flops with positive-edge triggering on a single chip.
• Provides TTL-compatible input logic levels for direct interfacing with standard digital systems.
• Delivers high-speed data storage and transfer capabilities with a 11 ns propagation delay.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose memory storage elements

Flip Flops Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official documentation to confirm the exact package type and pinout configuration. Ensure that the selected variant matches the required surface-mount technology specifications and thermal performance characteristics for the intended application environment.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop solution with TTL-compatible inputs is required. The SN74ACT series offers improved switching speeds compared to standard HC variants while maintaining CMOS output drive strength. Consider the 14-pin SOIC package constraints and verify compatibility with existing PCB layout requirements before finalizing the design.

Flip Flops Part Context

This part belongs to the SN74ACT family, which combines the speed of AS logic with the low power consumption of AC logic. The SN74ACT74 specifically provides dual flip-flops, making it suitable for applications requiring multiple data storage stages without consuming excessive board space or power budget.
