SN74ALS02ADR

Overview

The SN74ALS02ADR 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 an 8 mA low-level output current and -400 uA high-level output current. It is housed in a 14-pin SOIC package and supports surface-mount installation with operating temperatures between 0°C and +70°C.

Feature Summary

• Contains four independent 2-input NOR logic gates
• Advanced Low-power Schottky (ALS) technology for reduced power consumption
• Compatible with standard TTL input levels

Applications

• Digital logic signal processing
• Boolean function implementation
• General-purpose combinational logic circuits

Procurement Notes

Verify the specific suffix 'ADR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure the component matches the required SN74ALS02A series specifications for voltage and timing parameters before integration into the design.

Selection Notes

Select this component when designing systems requiring multiple NOR gates with moderate speed and low power dissipation. The ALS series offers a balance between performance and power efficiency compared to standard LS or AS families, suitable for general digital applications.

Part Context

This part belongs to the SN74ALS02A family of single-function logic gates manufactured by Texas Instruments. It is designed for use in various digital electronic systems where reliable NOR logic operations are required under standard industrial temperature conditions.

Replacement Considerations

Check for direct equivalents such as SN74ALS02AN or SN74ALS02AD if different packaging is needed. Verify pin compatibility and electrical characteristics against the original datasheet before substituting.
