SN74ACT11DG4

Overview

The SN74ACT11DG4 is a triple 3-input AND gate manufactured by Texas Instruments, belonging to the 74ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low quiescent current of 2 µA. The device provides high noise immunity with defined logic levels: 0.8 V for low and 2 V for high. It supports output currents of 24 mA for both high and low states. Propagation delay is specified at 9.5 ns at 5 V with 50 pF load. Operating temperature spans from -40°C to +85°C. It is housed in a 14-SOIC package.

Feature Summary

• Triple 3-input AND logic function
• High noise immunity with defined logic thresholds
• Low quiescent current consumption
• Symmetrical output drive capability

Applications

• Digital signal processing circuits
• Memory address decoding
• Control logic interfaces
• Microprocessor system gating

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status as per latest datasheet revisions. Check for end-of-life notifications or product change notices affecting availability. Ensure packaging matches required reel or tube specifications for assembly processes.

Selection Notes

Select this component for applications requiring standard 5V CMOS logic compatibility with enhanced switching speeds compared to legacy 74LS families. Verify input voltage levels match source drivers. Consider thermal management within the specified operating temperature range during PCB layout.

Part Context

Part of the Texas Instruments 74ACT family, designed for high-speed digital applications. Compatible with TTL inputs while offering CMOS performance. Provides a drop-in replacement for older 74S and 74LS equivalents in many designs, improving speed without changing power supply requirements.

Replacement Considerations

SN74ACT11D is a direct equivalent variant. SN74ACT11DR offers tape-and-reel packaging instead of tube. SN74ACT11PWR provides TSSOP-14 packaging alternative.
