74ACT08SC

Overview

The onsemi 74ACT08SC is a quad 2-input AND gate integrated circuit manufactured using advanced CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and features low static current consumption with a maximum of 4 µA. The device provides high drive capability, sourcing and sinking 24mA for both high and low output states. It supports surface-mount installation in a 14-SOIC package (0.154 inch width) and ensures reliable performance across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input AND gates into a single compact package
• Provides robust load driving capability with 24mA output current capacity
• Ensures signal integrity through defined logic levels at 0.8V (low) and 2V (high)
• Maintains low power consumption with minimal static current draw

Applications

• Digital signal processing circuits requiring logical conjunction operations
• Control systems utilizing parallel data path gating
• General-purpose logic interfacing between 5V compatible components

Procurement Notes

Verify the specific suffix 'SC' against official manufacturer documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with standard SOIC footprint layouts during PCB design. Confirm RoHS compliance status directly from the datasheet before final procurement decisions.

Selection Notes

Select this component when a quad 2-input AND function is required in a 5V logic environment. It is suitable for designs needing moderate drive strength without external buffers. Consider the 14-SOIC package constraints for board space. Verify that the 4.5V minimum supply voltage aligns with the system power rails.

Part Context

This part belongs to the 74ACT series, which bridges the performance gap between older TTL logic and modern CMOS technologies. It offers faster propagation delays than HC series devices while maintaining CMOS power efficiency. The 74ACT08 family is widely used in legacy system upgrades and mixed-technology digital designs.

Replacement Considerations

Direct substitutes include MC74ACT08DR2G from onsemi. Cross-manufacturer equivalents such as SN74ACT08DR from Texas Instruments are also available.
