MC74HC273ADWG

Flip Flops Overview

The MC74HC273ADWG is an octal D-type flip-flop from the onsemi 74HC logic family, housed in a 20-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 24 MHz. The device features single-ended inputs and outputs with non-inverting polarity. Key electrical parameters include a propagation delay of 145 ns at typical conditions, with output drive capabilities of -7.8 mA for high level and 7.8 mA for low level. It functions reliably across an extended temperature range from -55°C to +125°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops into a single unit for efficient data storage
• Provides positive-edge triggering mechanism for precise timing control
• Features a master reset function to initialize all flip-flop states simultaneously

Flip Flops Applications

Flip Flops Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment for the SOIC-20 form factor. Ensure compliance with RoHS directives if required by project standards. Cross-reference ordering suffixes to confirm tape-and-reel or tube packaging variants match procurement requirements. Validate humidity sensitivity levels prior to soldering processes.

Flip Flops Selection Notes

Select this component when an octal storage solution is required within the 74HC voltage and speed constraints. Consider the 20-pin SOIC footprint for surface-mount assembly compatibility. Evaluate the 2V to 6V operating range against system power rails. Compare propagation delays and output current capabilities against load requirements. Assess thermal performance within the specified -55°C to +125°C operational window.
