SN74F74NSR

Flip Flops Overview

The SN74F74NSR is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments 74F series. It features independent data (D) and clock (CP) inputs for each of its two circuits, along with separate direct clear (CLR) and preset (PRE) inputs that are also independent. The device provides complementary outputs (Q and Q-bar) and utilizes a 14-pin SOIC package. Key electrical parameters include a propagation delay of 6 ns, a minimum supply voltage of 4.5 V, and a maximum of 5.5 V. It supports TTL input levels and operates within a temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with dedicated control inputs
• Positive-edge triggering on the clock input for precise timing

• Complementary outputs available for versatile logic interfacing

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction in digital systems
• Frequency division and counting applications
• Data storage and buffering in microprocessor interfaces

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and environmental compliance. Confirm that the component matches the required logic family specifications and pinout configuration for your design. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards and RoHS directives.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with asynchronous control is required in high-speed logic designs. The 74F series offers faster switching speeds compared to standard 74LS equivalents. Ensure the design accommodates the specific input current requirements and power supply stability needed for reliable operation at the specified voltage range.

Flip Flops Part Context

This part belongs to the Texas Instruments 74F series, known for fast switching speeds in bipolar logic technology. The 'NSR' designation indicates a surface-mount SOIC package supplied in a reel format. It is functionally equivalent to other industry-standard dual D-flip-flop devices but adheres to TI's specific manufacturing tolerances and performance characteristics defined in its official datasheet.

Flip Flops FAQ

What is the trigger type for the SN74F74NSR?

The device uses positive-edge triggering, meaning the output changes state on the rising edge of the clock signal.

Are the clear and preset inputs synchronous or asynchronous?

The clear and preset inputs are asynchronous, allowing them to override the clock and data inputs immediately.
