SN74ALS02ANSR

Overview

The SN74ALS02ANSR is a quadruple 2-input positive-NOR gate from the Texas Instruments SN74ALS02A series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 12 ns. The device provides a low-level output current of 8 mA and a high-level output current of -400 uA. It is housed in a 14-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains four independent 2-input NOR logic gates within a single integrated circuit
• Delivers high-speed signal processing with a specified propagation delay of 12 ns
• Provides robust low-level output drive capability for interfacing with various loads

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing systems utilizing ALS series components
• Industrial control equipment operating within standard commercial temperature ranges

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the requested part matches the exact SN74ALS02ANSR designation to avoid discrepancies in pinout or electrical characteristics. Cross-reference datasheet revisions to confirm current manufacturing status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require multiple independent NOR gates with moderate speed requirements. The ALS series offers a balance between power consumption and switching speed suitable for general-purpose digital applications. Consider the 14-SOIC package dimensions for PCB layout compatibility and verify that the 4.5 V to 5.5 V supply voltage aligns with the system's power architecture.

Part Context

This component belongs to the SN74ALS02A family of logic gates manufactured by Texas Instruments. The ALS (Advanced Low-power Schottky) series is designed to provide improved performance over standard LS logic while maintaining lower power dissipation. The SN74ALS02A specifically implements the NOR logic function, serving as a fundamental building block for complex digital logic designs requiring negative-OR operations.
