SN74HCT273ANS

Flip Flops Overview

The SN74HCT273ANS is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HCT logic series. It features eight independent D-type flip-flops with a common clear input, packaged in a 20-pin SOIC (Small Outline Integrated Circuit) format. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation. It exhibits a propagation delay of 34 ns, with high-level output current capability of -4 mA and low-level output current of 4 mA. The component functions with TTL inputs and CMOS outputs, operating reliably across a temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops with a shared asynchronous clear function for synchronized data storage.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register arrays in digital logic systems
• Buffer memory applications requiring octal storage

Flip Flops Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with standard SOIC-20 footprints during PCB layout. Confirm RoHS compliance status through the latest product information sheet before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when interfacing TTL logic levels with CMOS outputs in an octal configuration. The HCT series ensures compatibility with standard 5V TTL systems while providing CMOS output characteristics. Consider the 20-pin SOIC package for surface-mount assembly requirements and verify thermal performance within the specified industrial temperature range.
