SN74AS11NSR

Overview

The SN74AS11NSR is a Texas Instruments logic gate featuring three independent 3-input positive-AND gates. It belongs to the AS (Advanced Schottky) series, utilizing bipolar technology for high-speed performance. The device is housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range from 0°C to +70°C. Key electrical characteristics include a low-level output current of 24 mA and a high-level output current of -8 mA. Propagation delay is typically 6 ns at 5 V with 50 pF load capacitance.

Feature Summary

• Provides three independent 3-input AND logic functions within a single integrated circuit
• Utilizes Advanced Schottky (AS) bipolar technology for enhanced switching speed
• Features standard TTL-compatible input and output levels for system integration

Applications

• Digital logic circuits requiring triple 3-input AND operations
• High-speed data processing systems utilizing AS series components
• Industrial control logic interfaces operating at standard 5V supply

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel specifications. Ensure the component matches the required logic family and pinout configuration for your design. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the manufacturer part number with official datasheets to validate technical parameters before procurement.

Selection Notes

Select this component when high-speed AND gating is required within a compact surface-mount footprint. The AS series offers superior speed compared to standard or LS variants while maintaining compatibility with existing TTL logic families. Consider the 14-pin SOIC package constraints and thermal management requirements for dense PCB layouts. Verify that the 5V supply voltage aligns with the rest of the system architecture.

Part Context

This component is part of the Texas Instruments SN74ASxx logic family, designed for applications demanding faster propagation delays than standard Schottky devices. The '11' designation specifically indicates a triple 3-input AND gate configuration. It serves as a high-performance alternative in digital systems where signal integrity and timing are critical factors.

Replacement Considerations

Compatible substitutes include SN74AS11N and SN74AS11NS. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
