MM74HC273WM

Flip Flops Overview

The MM74HC273WM is a high-speed CMOS octal D-type flip-flop manufactured by Fairchild Semiconductor. It features positive-edge triggering and non-inverting outputs within a single functional element. The device operates on a supply voltage range of 2V to 6V and utilizes a 20-SOIC surface-mount package with a width of 0.295 inches (7.50mm). It supports a maximum clock frequency of 78 MHz and includes a master reset function. The component exhibits a typical propagation delay of 23ns at 6V with a 50pF load, while maintaining a static current consumption of 8µA across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements in a single integrated circuit.
• Positive-edge triggered operation synchronized with the clock signal for precise timing control.
• Master reset functionality allows for immediate initialization of all output states regardless of input conditions.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Data buffering and temporary storage applications

Flip Flops Procurement Notes

Verify that the specific part number corresponds to the Fairchild Semiconductor manufacturer designation rather than other vendors using similar nomenclature. Confirm the package variant matches the standard 20-SOIC specification. Ensure compliance with RoHS directives if required for the target assembly process. Cross-reference the datasheet revision to confirm electrical characteristics align with design requirements.

Flip Flops Selection Notes

Select this component when an octal storage solution with positive-edge triggering is required for low-power CMOS designs. The wide supply voltage range accommodates various logic levels. Consider the 20-SOIC footprint for surface-mount assembly constraints. Evaluate the 78 MHz clock limit against system speed requirements to ensure adequate performance margins for the intended application frequency.

Flip Flops Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic circuits requiring multiple bits of storage. The MM74HC273WM provides a compact alternative to discrete flip-flop arrangements, simplifying board layout and reducing component count in complex digital processing architectures.
