SN74HCT74NSRE4

Flip Flops Overview

The SN74HCT74NSRE4 is a dual D-type edge-triggered flip-flop from the Texas Instruments SN74HCT74 series. It features independent data (D), preset (PRE), and clear (CLR) inputs for each of its two circuits, with complementary Q and /Q outputs. The device operates within a supply voltage range of 2V to 6V. Key electrical parameters include a maximum propagation delay of 30ns at 6V with 50pF load, a clock frequency of 60MHz, and output currents of 5.2mA. It utilizes a 14-SOIC package and supports an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Dual D-type edge-triggered flip-flops with independent control inputs
• CMOS output structure providing complementary signals
• Wide operating supply voltage compatibility
• Surface-mount packaging for automated assembly

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Timing and synchronization logic stages
• General-purpose digital storage elements

Flip Flops Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the tape-and-reel packaging format required for surface-mount production lines. Confirm that the specific variant matches the HCT logic family requirements for TTL-compatible input thresholds in your system design. Ensure the component meets the necessary RoHS compliance standards for your manufacturing region.

Flip Flops Selection Notes

Select this component when a dual flip-flop configuration is needed with CMOS outputs and wide voltage tolerance. The HCT series ensures compatibility with standard TTL logic levels while offering lower power consumption than older LS families. Consider the SOIC package dimensions and thermal characteristics for PCB layout constraints.

Flip Flops Part Context

This part belongs to the SN74HC/HCT/ACT/HCS logic families produced by Texas Instruments. These components are widely used in general-purpose digital electronics for state retention and data handling. The SN74HCT74 series specifically bridges the gap between HC speed and HCT input compatibility.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74HC74N and SN74HCT74N. Verify pinout compatibility and ensure that the replacement part maintains the same logic family input threshold characteristics if interfacing with TTL sources.
