SN74HCT74DRE4

Flip Flops Overview

The SN74HCT74DRE4 is a dual D-type flip-flop from Texas Instruments' HCT logic series, housed in an SOIC-14 surface-mount package. It operates on a supply voltage range of 4.5 V to 5.5 V with TTL-compatible inputs and CMOS outputs. The device features independent set and reset controls for each flip-flop, providing positive-edge triggering functionality. Key electrical parameters include a propagation delay of 25 ns at 5.5 V, output currents of ±4 mA, and a static current of 4 µA. It supports through-hole or surface-mount installation styles and functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type edge-triggered flip-flops with independent set and reset controls
• TTL-compatible input thresholds for direct interfacing with TTL systems
• CMOS output structure ensuring low power consumption and high noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose storage elements in digital logic systems

Flip Flops Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm material composition and RoHS compliance status. Ensure the SOIC-14 package dimensions match the target PCB footprint requirements. Confirm that the operating voltage range aligns with the system's power supply specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with TTL-compatible inputs is required in a surface-mount configuration. The HCT series ensures compatibility with standard 5V logic families while offering improved noise margins compared to older LS variants. Consider the SOIC-14 package for automated assembly processes where space efficiency is prioritized over through-hole mounting options.

Flip Flops Part Context

This part belongs to the SN74HCT74 family of dual D-type flip-flops manufactured by Texas Instruments. It is designed for use in general-purpose digital applications requiring reliable data storage and transfer capabilities. The HCT technology combines the speed of HC logic with the noise immunity and compatibility of TTL inputs, making it suitable for mixed-logic system designs.

Flip Flops Replacement Considerations

SN74HCT74DR is a compatible alternative from the same manufacturer with identical logical functionality but may differ in packaging quantity or specific manufacturing batch details.
