74AC20SC

Overview

The onsemi 74AC20SC is a dual 4-input NAND gate manufactured using AC CMOS technology. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features outputs capable of sourcing and sinking 24mA. Propagation delays are specified at 10ns maximum at 5V with 50pF load, and input leakage current is limited to 1.0µA.

Feature Summary

• Dual 4-input NAND logic function
• High output drive capability of 24mA
• Reduced quiescent supply current

Applications

• General digital logic processing
• Signal gating and switching
• Data path control circuits

Procurement Notes

Verify the specific package variant against the datasheet ordering information. Confirm that the component meets JEDEC lead-free standards (J-STD-020B). Ensure compatibility with the required voltage levels and temperature ranges for the target application environment before finalizing procurement.

Selection Notes

Select this component when a dual 4-input NAND configuration is required in a narrow SOIC package. Consider the 24mA output drive strength for direct interfacing with loads. Verify that the 2V to 6V supply range aligns with the system power architecture and that the propagation delay specifications meet the timing requirements.

Part Context

This part belongs to the 74AC series of high-speed CMOS logic devices. It provides equivalent functionality to standard TTL logic but operates at higher speeds with lower power consumption. The SC suffix specifically denotes the 14-lead Small Outline Integrated Circuit (SOIC) package format.

Replacement Considerations

Check for equivalents such as MC74AC20 or other 74AC20 variants from different manufacturers. Verify pinout compatibility and electrical characteristics match the original design requirements.
