MM74HCT273N

Flip Flops Overview

The MM74HCT273N is an octal D-type flip-flop manufactured by Fairchild Semiconductor, belonging to the 74HCT logic series. It features eight positive-edge triggered D-type flip-flops with a common clock and master reset input. The device operates within a supply voltage range of 4.5V to 5.5V. It utilizes a 20-pin Dual In-line Package (DIP) for through-hole mounting. The outputs are non-inverting, providing true output states corresponding to the data inputs upon valid clock transitions.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type flip-flops
• Positive-edge triggering synchronized by a single common clock signal
• Master reset function forces all outputs low independently of clock and data
• Compatible with standard TTL input levels due to HCT logic family characteristics

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in digital control systems
• Data buffering between asynchronous logic blocks
• State holding elements in sequential logic designs

Flip Flops Procurement Notes

Verify manufacturer authenticity as Fairchild Semiconductor operations have transitioned. Confirm package integrity for 20-DIP specifications. Check RoHS compliance status against current environmental regulations. Validate pinout compatibility with existing PCB footprints before integration into production assemblies.

Flip Flops Selection Notes

Select this component when through-hole mounting is required for octal flip-flop applications. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider thermal dissipation requirements for DIP packages in enclosed environments. Verify timing constraints match the specific propagation delay characteristics of the HCT series.

Flip Flops FAQ

What is the trigger type of the MM74HCT273N?

The device uses positive-edge triggering, meaning outputs change state on the LOW-to-HIGH transition of the clock signal.

How does the master reset input function?

A LOW signal on the master reset input forces all eight outputs to a LOW state, regardless of the clock or data input conditions.
