MM74HCT05M

Inverter Gates Overview

The MM74HCT05M is a hex inverter fabricated using advanced silicon-gate CMOS technology. It features open-drain outputs and operates within a supply voltage range of 4.5V to 5.5V. The device provides high noise immunity and supports TTL-compatible input levels. It is housed in a 14-pin SOIC package and is designed for industrial temperature ranges from -40°C to +85°C.

Inverter Gates Feature Summary

• Hex inverter configuration with six independent channels
• Open-drain output structure suitable for wired-OR applications
• TTL-compatible input logic levels for direct interfacing
• High noise immunity inherent to CMOS technology

Inverter Gates Applications

• Signal inversion in digital logic circuits
• Wired-OR bus configurations requiring open-drain outputs
• Interface between TTL and CMOS logic families
• Level shifting applications with pull-up resistors

Inverter Gates Procurement Notes

Verify the current production status as sources indicate this part may be obsolete or discontinued by Fairchild Semiconductor. Confirm availability through authorized distributors or onsemi, which acquired Fairchild's semiconductor business. Ensure the specific suffix 'M' corresponds to the required SOIC package variant when sourcing replacements.

Inverter Gates Selection Notes

Select this component when an open-drain hex inverter is required for TTL-to-CMOS interfacing. The HCT series ensures compatibility with standard TTL logic voltages while offering CMOS performance benefits. Consider the open-drain nature for applications needing multiple outputs to share a common line or drive higher voltage loads via external pull-ups.

Inverter Gates Part Context

This component belongs to the 74HCT logic family, which bridges the gap between older TTL standards and modern CMOS technologies. The MM74HCT05M specifically provides hex inversion with open-drain outputs, distinguishing it from standard push-pull inverters like the 74HCT04. It is part of a broader portfolio of logic functions available from Fairchild and its successor entity.

Inverter Gates Replacement Considerations

Check for equivalents such as the MM74HCT05N or other manufacturers' 74HCT05 variants. Verify pinout compatibility and electrical specifications, particularly the open-drain output capability and supply voltage range, before substituting.
