SN74HC74NG4

Flip Flops Overview

The SN74HC74NG4 is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features CMOS output types and accepts CMOS input signals. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole installation in a PDIP-14 package. Key electrical parameters include a propagation delay of 175 ns, with high-level output current at -5.2 mA and low-level output current at 5.2 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Contains two independent D-type flip-flops with positive-edge triggering capability
• Includes dedicated clear and preset inputs for direct state control
• Compatible with standard CMOS logic families for input and output interfaces

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Basic digital memory storage elements

Flip Flops Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific lead-free and environmental compliance requirements intended for the project. Confirm that the PDIP-14 through-hole package aligns with the printed circuit board footprint design. Ensure the manufacturer identification matches Texas Instruments specifications to guarantee authentic component sourcing.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop solution is required with through-hole mounting compatibility. The HC series offers broad voltage flexibility between 2 V and 6 V, suitable for various digital logic levels. Consider the 175 ns propagation delay against system timing requirements before finalizing the design choice.

Flip Flops Part Context

This part belongs to the SN74HCxx family of high-speed CMOS logic devices produced by Texas Instruments. The HC series is widely utilized for general-purpose digital applications requiring standard logic functionality. The SN74HC74 variant specifically provides dual flip-flop capabilities within a single integrated circuit package.

Flip Flops Replacement Considerations

The SN74HC74N serves as a direct functional equivalent without the G4 suffix designation.
