74AC11SCX

Overview

The onsemi 74AC11SCX is a Triple 3-Input AND Gate belonging to the 74AC logic series. It contains three independent AND gates, each with three inputs and one output. The device operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature range from -40°C to +85°C. It is housed in a 14-Lead Small Outline Integrated Circuit (SOIC) package. The outputs are capable of sourcing and sinking 24mA. Quiescent supply current is typically 2.0µA at 5.5V.

Feature Summary

• Contains three independent 3-input AND logic gates
• Outputs provide high drive capability with 24mA source/sink capacity
• Reduced quiescent supply current compared to previous generations

Applications

• Digital logic circuit design
• Signal gating and selection
• Microprocessor interface circuits

Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as per datasheet specifications. Confirm the manufacturer origin, noting historical Fairchild Semiconductor documentation now managed by onsemi. Ensure the SOIC-14 package dimensions match JEDEC MS-012 standards for board layout compatibility.

Selection Notes

Select this component when multiple independent 3-input AND functions are required in a single package. The 74AC series offers higher speed than HC variants while maintaining CMOS power consumption. Verify that the 24mA output drive meets load requirements and that the 2V to 6V supply range aligns with system voltage rails.

Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices. The 74AC11 specifically implements triple 3-input AND functionality. It is functionally compatible with other 74AC logic families but provides distinct gate count and input configuration compared to dual 4-input or single 2-input variants.

Replacement Considerations

Direct replacements include MC74AC11DR from onsemi or SN74AC11D from Texas Instruments. Verify pinout compatibility and ensure equivalent propagation delay and drive strength specifications.
