SN74F74DG4

Flip Flops Overview

The SN74F74DG4 is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments F/FAST logic family. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V. The device features a maximum propagation delay of 9.2ns at nominal voltage and supports a maximum operating frequency of 70MHz. It provides a maximum output current of 20mA for both high and low states. The component is housed in a 14-pin SOIC package and functions reliably across an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Dual configuration containing two independent positive-edge-triggered D-type flip-flops within a single package.
• Integrated asynchronous clear and preset inputs for immediate state control independent of clock signals.
• Complementary outputs provide both true and inverted logic states for each flip-flop element.

Flip Flops Applications

• Data storage and latching in digital logic circuits
• Shift register construction for serial-to-parallel data conversion
• Frequency division and counting applications

Flip Flops Procurement Notes

Verify that the ordering suffix 'G4' confirms lead-free status and compliance with RoHS3 standards as documented by Texas Instruments. Confirm the package designation matches the SOIC-14 physical dimensions and pinout requirements for your PCB layout. Ensure the operating temperature grade aligns with the specified 0°C to 70°C range for your intended environment.

Flip Flops Selection Notes

Select this component when high-speed switching is required compared to standard 74 series logic, while maintaining compatibility with 5V TTL interfaces. The F/FAST technology offers faster propagation delays than HC or HCT families. Consider the dual flip-flop density if space efficiency is critical for designs requiring multiple storage elements.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74F series, which utilizes Fast Schottky (F) technology to achieve higher speed performance than standard bipolar logic. The SN74F74 specifically addresses the need for dual edge-triggered storage with direct control inputs, serving as a fundamental building block for synchronous digital systems requiring precise timing control.

Flip Flops Replacement Considerations

Public confirmed substitutes include SN74F74DRG4 and SN74F74DRE4. These variants share identical logical functionality and electrical specifications but differ in packaging format or manufacturing revision codes.
