SN74F74DR

Flip Flops Overview

The SN74F74DR is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' SN74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum frequency of 100 MHz. The device features two independent circuits in a 14-pin SOIC package, with a typical propagation delay of 6 ns. It provides complementary outputs and includes preset and clear inputs for direct control. The component is designed for surface-mount installation and functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent data paths
• Direct asynchronous preset and clear inputs for immediate state control
• Complementary outputs (Q and Q-bar) for versatile logic interfacing
• High-speed operation supporting frequencies up to 100 MHz

Flip Flops Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Shift register construction for data storage and transfer
• Frequency division and timing signal generation
• Digital state storage in microprocessor-based systems

Flip Flops Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the requested variant matches the required pinout and electrical specifications for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when dual independent D-type storage elements are required in a compact surface-mount format. The SN74F series offers higher speed performance compared to standard 74LS equivalents, making it suitable for applications demanding faster switching times. Consider the 14-pin SOIC package constraints and thermal requirements during PCB layout design to ensure reliable operation within the specified temperature range.

Flip Flops Part Context

The SN74F74DR belongs to the SN74F (FAST) logic family, characterized by high-speed performance using Schottky diode technology. This family bridges the gap between standard TTL speeds and ECL complexity, providing efficient digital logic solutions. The 'DR' suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes, distinguishing it from through-hole or tube-packaged variants.
