MM74HCU04MX

Inverter Gates Overview

The MM74HCU04MX is a hex inverter integrated circuit manufactured by Fairchild Semiconductor. It utilizes advanced silicon-gate CMOS technology to achieve operating speeds comparable to LS-TTL gates while maintaining low power consumption typical of standard CMOS devices. The device features high noise immunity and the capability to drive up to 15 LS-TTL loads. All inputs are protected from static discharge damage via internal diode clamps connected to VCC and ground. The component operates within a supply voltage range of 2V to 6V.

Inverter Gates Feature Summary

• Advanced silicon-gate CMOS technology for high-speed operation with low power dissipation
• High noise immunity suitable for demanding logic environments
• Internal input protection against electrostatic discharge (ESD) damage

Inverter Gates Applications

• Memory address decoding
• Data routing applications
• General-purpose logic inversion

Inverter Gates Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor has undergone corporate restructuring and its assets were acquired by onsemi. Confirm that the specific part number corresponds to the original Fairchild production run rather than subsequent onsemi manufacturing. Ensure the datasheet revision matches the required specifications for your design.

Inverter Gates Selection Notes

Select this component when a hex inverter is required that offers performance similar to LS-TTL but with the lower power characteristics of CMOS. It is appropriate for designs needing ESD-protected inputs and the ability to interface directly with multiple LS-TTL loads without additional buffering.

Inverter Gates Part Context

This part belongs to the 74HCU series, which provides unbuffered hex inverters. It is functionally and pin-out compatible with the standard 74LS logic family. The 'M' suffix typically indicates a surface-mount package variant, distinguishing it from through-hole versions like the MM74HCU04N.

Inverter Gates Replacement Considerations

Functionally equivalent parts include the MM74HCU04N and other variants within the 74HCU family. Cross-referencing with 74HC04 or 74LVC04A may be possible depending on voltage requirements, though electrical characteristics differ.
