MM74HCT05SJ

Inverter Gates Overview

The MM74HCT05SJ is a hex inverter integrated circuit manufactured by Fairchild Semiconductor, utilizing 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 is housed in a 14-lead Small Outline (SOIC) package with a width of 3.90mm. Key electrical specifications include a maximum propagation delay of 20ns at 5V with a 50pF load, high-level output current of 6mA, and low quiescent power consumption.

Inverter Gates Feature Summary

• Hex inverter configuration with six independent channels
• Open-drain output structure for wired-OR applications
• CMOS technology ensuring low static power dissipation
• Industrial temperature range operation capability

Inverter Gates Applications

• TTL-to-CMOS level translation interfaces
• Clock signal buffering and inversion
• Memory address decoding circuits
• General-purpose logic inversion tasks

Inverter Gates Procurement Notes

Verify the specific suffix SJ against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm whether the component is actively produced or classified as obsolete, as availability may be limited. Ensure the supplier provides original documentation to validate the silicon-gate CMOS fabrication process and electrical characteristics.

Inverter Gates Selection Notes

Select this component when an open-drain output is required for driving higher voltages or implementing wired-logic configurations. The HCT series ensures direct compatibility with TTL inputs while maintaining CMOS noise immunity. Consider the 14-SOIC package constraints for PCB layout and thermal management during selection.

Inverter Gates Part Context

This part belongs to the 74HCT logic family, designed for high-speed CMOS operations compatible with standard TTL logic levels. The MM74HCT05 variant specifically provides open-drain outputs, distinguishing it from standard push-pull inverters like the MM74HCT04. It serves as a fundamental building block in digital systems requiring signal inversion with flexible output drive capabilities.

Inverter Gates Replacement Considerations

Check for equivalents such as MM74HCT05M or MM74HCT05N, noting that some variants may have different packaging or status. Verify if the MM74HCT04 is suitable if open-drain outputs are not strictly required. Consult ON Semiconductor resources due to Fairchild's integration for updated part nomenclature.
