SN74AS11N

Overview

The SN74AS11N is a Texas Instruments logic gate belonging to the AS (Advanced Schottky) series. It contains three independent 3-input AND gates housed in a 14-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting. Key electrical specifications include a propagation delay of 6 ns, a low-level output current capability of 20 mA, and a high-level output current of -2 mA. It functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Features Advanced Schottky technology for high-speed switching performance with reduced power consumption compared to standard TTL.
• Provides three independent 3-input AND logic functions within a single integrated circuit package.
• Delivers strong output drive capabilities suitable for interfacing with various digital loads.

Applications

• Digital logic circuits requiring fast AND operations
• Microprocessor-based system address decoding
• General-purpose combinatorial logic design

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the PDIP-14 package matches your board layout requirements. Check for any recent Product Change Notifications or RoHS compliance updates directly from the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when high-speed logic performance is required alongside moderate power dissipation constraints. The AS series offers a balance between speed and power, making it suitable for applications faster than LS series but less power-intensive than AC/ACT families. Ensure the 14-pin DIP form factor aligns with your assembly process.

Part Context

This component is part of the SN74AS11 family, which utilizes Advanced Schottky semiconductor technology. It serves as a high-speed alternative to standard logic gates, offering improved switching speeds while maintaining compatibility with traditional TTL voltage levels and interface standards.

Replacement Considerations

SN74ALS11N: Offers lower power consumption with slightly slower speed. SN74LS11N: Standard TTL version with significantly higher power usage and slower propagation delay. SN74ACT11N: CMOS technology providing lower power and wider voltage tolerance but different input characteristics.
