SN74HCT374NSR

Flip Flops Overview

The SN74HCT374NSR is an octal D-type flip-flop from the Texas Instruments 74HCT logic family, housed in a 20-pin SOIC surface-mount package. It features eight non-inverting D-type edge-triggered flip-flops with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 40 MHz. Key electrical parameters include a propagation delay of 46 ns at 5.5 V with 150 pF load, and output drive currents of ±6 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus structures with controlled enable/disable functionality
• CMOS-compatible inputs with TTL-level thresholds ensuring compatibility with standard digital logic systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems
• Buffering and latching operations on system buses

Flip Flops Procurement Notes

Verify the specific suffix 'SR' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Flip Flops Selection Notes

Select this component for designs requiring high-density octal storage in a compact surface-mount footprint. The HCT series offers superior noise immunity compared to standard HC logic while maintaining CMOS power efficiency. Consider the 46 ns propagation delay and 40 MHz clock limit when designing high-speed timing-critical paths.

Flip Flops Part Context

This part belongs to the widely adopted 74HCT logic family, designed as a high-speed CMOS equivalent to TTL logic. The SN74HCT374 variant specifically provides octal storage capabilities. It serves as a standard building block for sequential logic design in industrial and consumer electronics, offering reliable performance in general-purpose digital applications.

Flip Flops Replacement Considerations

SN74HCT374N (PDIP package), SN74HCT374DWR (SOIC-20, different tape/reel option). Verify pinout compatibility and electrical characteristics before substitution.
