DM7404M

Inverter Gates Overview

The DM7404M is a hex inverter integrated circuit belonging to the TTL/H/L series. It contains six independent single-input inverters housed in a 14-pin Small Outline Integrated Circuit (SOIC) package, specifically designated as SOP14,.25. The device operates within a standard temperature range with a maximum operating temperature of 70 °C. Electrical characteristics include a maximum low-level output current of 0.016 A. The component utilizes plastic/epoxy for its body material and features 14 terminals arranged in a dual-row configuration.

Inverter Gates Feature Summary

• Contains six independent single-input inverter gates
• Utilizes Advanced Oxide-Isolated Ion-Implanted Schottky process technology
• Provides functional and pin compatibility with 74LS and Schottky counterparts

Inverter Gates Applications

• Memory system buffer interfaces
• Microprocessor system signal inversion
• Communication system data line buffering

Inverter Gates Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement, as historical Fairchild documentation indicates non-compliance with certain environmental directives. Confirm that the SOIC-14 package dimensions match the target PCB footprint requirements. Ensure the supplier provides traceability to the original manufacturer specifications for the TTL/H/L series logic family.

Inverter Gates Selection Notes

Select this component when designing circuits requiring multiple inverted signals within a compact surface-mount form factor. The device offers switching performance similar to LS-TTL while maintaining lower power dissipation compared to standard Schottky logic. Consider the 70 °C maximum operating temperature limit for thermal management in enclosed environments.

Inverter Gates Part Context

This part belongs to the Fairchild Semiconductor DM74AS series, which comprises Advance Schottky 3-state bus drivers and receivers. While the DM74AS244 datasheet explicitly details the series' oxide-isolated ion-implanted Schottky process, the DM7404M represents the inverter variant within this high-speed logic family, designed for memory, microprocessor, and communication applications.

Inverter Gates Replacement Considerations

The DM7404M is functionally and pin-compatible with 74LS and Schottky counterpart inverters. Verify that substitute parts maintain the same SOIC-14 package outline and electrical characteristics for direct replacement in existing designs.
