SN74HCT374PWT

Flip Flops Overview

The SN74HCT374PWT is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the HCT logic series, featuring TTL-compatible inputs and CMOS outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides a propagation delay of 46 ns and supports output currents of -6 mA (high) and 6 mA (low). Packaged in a 20-pin SOIC format, it functions reliably across an industrial temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Features eight independent D-type flip-flops triggered on the positive edge of the clock signal.
• Provides three-state outputs for effective bus-oriented memory mapping applications.
• Ensures compatibility with standard TTL logic systems through dedicated input structures.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• High-speed buffering operations

Flip Flops Procurement Notes

Verify the specific suffix 'PWT' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target assembly process. Confirm that the operating voltage aligns strictly with the 4.5 V to 5.5 V specification to prevent functional failure or damage.

Flip Flops Selection Notes

Select this component when interfacing between high-speed CMOS logic and legacy TTL systems requiring octal storage. The HCT series offers superior noise immunity compared to standard HC devices while maintaining pin compatibility. Consider the SOIC-20 package dimensions for PCB layout constraints and verify thermal dissipation capabilities within the specified ambient temperature limits.

Flip Flops Part Context

This part is a member of the SN74HCT374 family, which includes variants such as SN74HCT374DWR and SN74HCT374DBR. These components share identical logical functionality but differ in packaging styles like SOIC, SSOP, and TSSOP. The HCT series serves as a bridge technology, enabling seamless integration between older TTL-based designs and modern CMOS architectures.

Flip Flops Replacement Considerations

SN74HCT374DWR and SN74HCT374DBR are functionally equivalent alternatives offering different packaging options.
