MM74HCU04SJ

Inverter Gates Overview

The MM74HCU04SJ is a hex inverter manufactured by onsemi, utilizing advanced silicon-gate CMOS technology. It provides six independent inverters within a single package. The device operates with a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to +125°C. Typical propagation delay is 7 ns at 5 V, with guaranteed limits up to 13 ns under specific conditions. Quiescent power consumption is typically 10 µA maximum at room temperature. The logic family is functionally and pin-out compatible with the standard 74LS logic family.

Inverter Gates Feature Summary

• Advanced silicon-gate CMOS technology for high-speed operation similar to LS-TTL gates
• High noise immunity with internal diode clamps protecting inputs from static discharge damage
• Ability to drive fifteen LS-TTL loads directly
• Functionally and pin-out compatible with the standard 74LS logic family

Inverter Gates Applications

• Crystal oscillator circuits
• Stable RC oscillator configurations
• Schmitt trigger applications

Inverter Gates Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and Pb-free status as specified in the datasheet. Ensure proper handling procedures are followed due to static sensitivity, despite internal protection diodes. Validate that the SOIC-14 package dimensions match the design requirements before integration into the final assembly process.

Inverter Gates Selection Notes

Select this component when a hex inverter with LS-TTL speed performance and low power consumption is required. It is suitable for designs needing compatibility with existing 74LS logic architectures. Consider the wide operating temperature range for industrial or automotive environments. Verify input voltage levels against the VIH and VIL specifications for the chosen supply voltage.

Inverter Gates Part Context

This part belongs to the MM74HCU04 series, which represents the HCU (High-Speed CMOS) logic family. These devices bridge the performance gap between standard HC logic and older LS-TTL technologies. The SJ suffix indicates a specific packaging variant, typically associated with tube packaging for surface-mount applications. This series is designed for general-purpose digital logic inversion tasks.

Inverter Gates Replacement Considerations

Direct substitutes include MM74HCU04MTCX and MM74HCU04MX. Cross-family replacements like MM74HC04 variants may require level shifting verification. Ensure any replacement maintains the same pinout and electrical characteristics, particularly propagation delay and output drive capability.
