SN74F74N

Flip Flops Overview

The SN74F74N is a dual D-type flip-flop from the Texas Instruments SN74F series, housed in a 14-pin PDIP package. It features TTL inputs and outputs with non-inverting and inverting Q outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8 ns, a high-level output current of -1 mA, and a low-level output current of 20 mA. It supports through-hole mounting and functions within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains two independent D-type flip-flops with positive-edge triggering for data storage applications.
• Provides both non-inverting (Q) and inverting (Q') outputs for each flip-flop stage.
• Utilizes standard TTL input logic levels compatible with existing digital circuitry.

Flip Flops Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Digital signal processing and timing control systems
• General-purpose shift register configurations

Flip Flops Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the PDIP-14 package type and SN74F series designation on the physical unit. Ensure the part meets the specified 0°C to +70°C operating temperature range requirements for your specific application environment before integration.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop solution with fast switching speeds is required. The SN74F series offers higher performance than standard LS variants but consumes more power. Consider the 14-pin DIP package for prototyping or through-hole assembly needs where space constraints are less critical than ease of handling.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74F logic family, known for high-speed bipolar transistor technology. It serves as a fundamental building block for sequential logic design. The 'N' suffix indicates the standard plastic dual in-line package configuration suitable for general-purpose electronic assemblies.

Flip Flops FAQ

What is the trigger mechanism for the SN74F74N?

The flip-flops are triggered on the positive-going edge of the clock signal.

Does the SN74F74N have asynchronous preset and clear inputs?

Yes, each flip-flop includes asynchronous preset and clear inputs that operate independently of the clock.
