DM7420N

Inverter Gates Overview

The DM7420N is a dual 4-input NAND gate integrated circuit manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and features TTL logic compatibility. The device is housed in a 14-pin PDIP package with a lead-free, plastic construction. It supports through-hole mounting and functions as a standard logic gate for digital circuits.

Inverter Gates Feature Summary

• Contains two independent NAND gates performing the logic function
• Compatible with TTL logic levels
• Lead-free plastic packaging

Inverter Gates Applications

• Digital logic circuits requiring NAND functionality
• TTL-based system designs
• General-purpose switching applications

Inverter Gates Procurement Notes

Verify the specific manufacturer lot and date code upon receipt, as components may be sourced from various distributors or secondary markets. Confirm that the physical marking matches the DM7420N designation exactly. Ensure the package integrity is intact and free from damage before integration into the final assembly.

Inverter Gates Selection Notes

Select this component when a dual 4-input NAND gate is required in a through-hole DIP-14 package. It serves as a direct replacement for other manufacturers' equivalents in the 7420 series. Consider the 5V supply requirement and TTL input/output characteristics during schematic design.

Inverter Gates Part Context

This part belongs to the standard 7400 series of logic ICs, specifically the 7420 family which provides dual 4-input NAND gates. It is widely used in legacy and industrial systems where through-hole technology is preferred. The 'DM' prefix typically indicates a commercial grade temperature range and specific packaging style.
