SN74HCT273DW

Flip Flops Overview

The SN74HCT273DW is an octal D-type flip-flop from Texas Instruments' HCT logic series, housed in a 20-pin SOIC package. It features non-inverting outputs and a master clear function. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 34 ns, with high-level output current at -4 mA and low-level output current at 4 mA. It supports TTL input types and CMOS output types, functioning reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering into a single unit.
• Includes a dedicated master clear input to asynchronously reset all flip-flops simultaneously.
• Provides TTL-compatible inputs for direct interfacing with standard logic families.
• Delivers non-inverting outputs suitable for data storage and bus holding applications.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package configuration. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability records. Cross-reference the manufacturer part number against the latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Flip Flops Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output performance. The HCT series ensures noise immunity while maintaining speed appropriate for general-purpose digital logic. Consider the SOIC-20 package for space-constrained printed circuit board designs requiring surface-mount technology.
