SN74LS02DRE4

Inverter Gates Overview

The SN74LS02DRE4 is a quad 2-input positive-NOR gate integrated circuit manufactured by Texas Instruments. It belongs to the LS (Low-power Schottky) logic series and is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a .25-inch body width. The device operates within a standard voltage range of 4.75 V to 5.25 V and supports an operating temperature range from 0 °C to 70 °C. It features complementary outputs and has a maximum low-level output current of 16 mA.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR gates for complex logic implementation
• Utilizes Low-power Schottky technology for improved speed and power efficiency
• Provides complementary output polarity for flexible signal interfacing

Inverter Gates Applications

• Digital logic circuits requiring NOR functionality
• Signal processing systems using TTL-compatible logic levels
• Industrial control applications within standard commercial temperature ranges

Inverter Gates Procurement Notes

Verify the specific suffix 'RE4' against official Texas Instruments documentation to confirm lead-free status, RoHS compliance, and tape-and-reel packaging specifications. Ensure the SOIC-14 footprint matches the target PCB design. Confirm that the LS logic family characteristics align with the system's voltage and timing requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR configuration is required within the LSTTL family. It serves as a direct replacement for other SN74LS02 variants differing only in packaging or reel specifications. Consider the 14-pin SOIC form factor for surface-mount assembly needs. Verify compatibility with existing 5V logic levels and ensure thermal management suits the 0 to 70 °C operating environment.

Inverter Gates Part Context

This part is a member of the Texas Instruments SN74LSxx series, which defines Low-power Schottky TTL logic devices. The SN74LS02 specifically provides four independent 2-input NOR gates. The 'D' indicates the SOIC package type, while 'RE4' typically denotes environmental compliance and reel packaging. This series is widely used in general-purpose digital electronics where moderate speed and low power consumption are balanced.

Inverter Gates Replacement Considerations

Compatible substitutes include SN74LS02DR and SN74LS02N, provided the package type (SOIC vs. DIP) and reel specifications match the application requirements. Verify that alternative manufacturers offer equivalent LS-series electrical characteristics and pinout configurations.
