DM74ALS27M

Inverter Gates Overview

The DM74ALS27M is a Triple 3-Input NOR Gate manufactured by Fairchild Semiconductor, belonging to the Advanced Low-power Schottky (ALS) logic series. It features three independent NOR gates, each with three inputs, housed in a 14-Lead Small Outline Integrated Circuit (SOIC) package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation. It is designed for commercial temperature ranges from 0°C to +70°C.

Inverter Gates Feature Summary

• Provides three independent 3-input NOR logic functions
• Advanced Low-power Schottky technology for improved speed and power efficiency
• Compatible with standard TTL logic levels

Inverter Gates Applications

• Digital logic circuit design
• Computer peripheral interfaces
• Control systems requiring NOR logic functions

Inverter Gates Procurement Notes

Verify the manufacturer origin, as onsemi acquired Fairchild Semiconductor's logic business. Confirm the specific suffix 'M' denotes the SOIC-14 package variant. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Check for lead-free status and packaging specifications against current datasheets.

Inverter Gates Selection Notes

Select this component when three independent 3-input NOR gates are required in a compact surface-mount form factor. The ALS series offers a balance of switching speed and power consumption suitable for general-purpose digital applications. Consider pin compatibility with existing designs using standard 14-pin SOIC footprints.

Inverter Gates Part Context

This part belongs to the DM74ALS family of logic ICs, which utilizes Advanced Low-power Schottky technology. This series was designed to offer better performance than standard LS logic while maintaining lower power dissipation. The DM74ALS27M specifically implements the NOR function, distinct from NAND or AND gate variants within the same family.

Inverter Gates Replacement Considerations

Check for direct equivalents such as the DM74ALS27N (DIP package) if through-hole mounting is needed. Verify functional compatibility with other ALS-series NOR gates from different manufacturers, ensuring voltage and timing parameters align.
