MM74HCU04SJ

Inverter Gates Overview

The MM74HCU04SJ is a hex inverter integrated circuit manufactured by Fairchild Semiconductor, belonging to the 74HCU logic family. It features six independent inverters within a single package. The device utilizes advanced silicon-gate CMOS technology to achieve operating speeds comparable to LS-TTL gates while maintaining low power consumption typical of standard CMOS circuits. It operates with a supply voltage range of 2V to 6V and includes internal diode clamps on all inputs for static discharge protection. The component is housed in a 14-SOP surface-mount package.

Inverter Gates Feature Summary

• Unbuffered hex inverter design utilizing advanced silicon-gate CMOS technology
• High noise immunity with capability to drive 15 LS-TTL loads
• Input protection against static discharge damage via internal diode clamps

Inverter Gates Applications

• General-purpose signal inversion in digital logic circuits
• Clock signal conditioning and buffering
• Interface between CMOS logic stages and TTL-compatible loads

Inverter Gates Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entity, as production lines may have transferred. Confirm the specific suffix SJ corresponds to the intended 14-SOP packaging and pinout configuration. Ensure the datasheet revision matches the required electrical specifications for your application environment. Cross-reference the part number with current distributor catalogs to confirm availability status and lead times.

Inverter Gates Selection Notes

Select this component when unbuffered inversion is required alongside high-speed performance similar to LS-TTL. It is suitable for applications demanding low quiescent power consumption and robust noise immunity. Consider the 2V to 6V supply range compatibility with your system voltage levels. Verify that the 14-SOP package fits your PCB layout constraints and assembly capabilities.

Inverter Gates Part Context

This part belongs to the 74HCU series, which offers high-speed operation comparable to LS-TTL but with CMOS power characteristics. The 'MM' prefix typically denotes military or extended temperature grade variants from Fairchild, though commercial equivalents exist. The HCU family is functionally and pin-out compatible with standard 74LS logic families, facilitating direct replacement in many legacy designs.

Inverter Gates Replacement Considerations

Direct substitutes include MM74HCU04M (tape and reel) and MM74HCU04N (DIP). Other manufacturers offer equivalent parts such as SN74HCU04 or MC74HCU04. Verify pin compatibility and electrical parameters before substitution.
