74ACT04SCX

Overview

The onsemi 74ACT04SCX is a hex inverter integrated circuit manufactured using silicon gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports high-speed logic applications with propagation delays typically around 7 ns at 5 V with 50 pF load capacitance. The device features six independent inverters, each with one input, housed in a 14-SOIC surface-mount package. It provides robust output drive capabilities with maximum source and sink currents of 24 mA. The component is rated for an extended industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Six independent inverting channels implemented in a single compact package
• High-speed switching performance suitable for demanding digital logic applications
• Strong output drive capability supporting direct interfacing with loads
• Compliant with RoHS standards and designed for reliable industrial operation

Applications

• General-purpose signal inversion in digital logic circuits
• Clock signal generation and conditioning systems
• Data bus buffering and line driving applications
• Memory interface logic and control circuitry

Procurement Notes

Verify the specific suffix 'SCX' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 14-SOIC footprint matches the target PCB design guidelines. Ensure the 4.5 V to 5.5 V supply voltage requirement aligns with the system power rails. Check for any recent Product Change Notifications regarding pinout or electrical specifications before finalizing procurement.

Selection Notes

Select this component when six independent inverters are needed in a surface-mount format. The ACT series offers a balance of speed and power consumption compared to standard TTL or AC families. Consider the 24 mA output current if driving moderate capacitive loads directly. Verify that the 14-pin SOIC package dimensions fit within the available board space constraints.

Part Context

This part belongs to the 74ACT logic family, which bridges the performance gap between older TTL and newer high-speed CMOS technologies. The 74ACT04 variant specifically provides hex inversion functionality. The 'SCX' designation indicates the specific package style and reel packaging format used by onsemi for distribution.

Replacement Considerations

Direct substitutes include MC74ACT04DR2G from onsemi in a different package. Cross-manufacturer equivalents such as SN74ACT04DR from Texas Instruments offer similar electrical characteristics but require verification of pin compatibility and package dimensions.
