SN74LVC02ADR

Inverter Gates Overview

The SN74LVC02ADR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments in the LVC logic series. It operates from a supply voltage of 1.65V to 3.6V and supports inputs driven by 3.3V or 5V devices, enabling use as a translator in mixed-voltage systems. The device features a maximum propagation delay of 4.4ns at 3.3V and typical output ground bounce of 2V at VCC = 3.3V. It provides latch-up performance exceeding 250mA per JESD 17 specifications and is available in a 14-pin SOIC (D) package.

Inverter Gates Feature Summary

• Operates with input voltages up to 5.5V while powered by lower supply rails
• Supports translation between 3.3V and 5V system environments
• Provides high latch-up protection exceeding 250mA

Inverter Gates Applications

• Mixed 3.3V/5V system signal translation
• Digital logic implementation requiring NOR functionality
• Portable electronics utilizing low voltage operation

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'ADR' corresponds to the SOIC-14 tape and reel configuration. Confirm the required temperature range matches the SN74LVC02A commercial grade (-40°C to 85°C or -40°C to 125°C). Ensure ESD handling precautions are followed during assembly due to CMOS sensitivity.

Inverter Gates Selection Notes

Select this component for applications requiring four independent 2-input NOR gates in a compact surface-mount package. It is suitable for designs needing compatibility with both 3.3V and 5V I/O levels without external level shifting components. Consider thermal resistance values when designing PCB layouts for high-density applications.

Inverter Gates Part Context

This part belongs to the SNx4LVC02A family of quadruple 2-input positive-NOR gates. The 'SN74' prefix indicates commercial grade availability, while 'LVC' denotes Low-Voltage CMOS technology. The 'DR' suffix specifies the SOIC package and tape-and-reel shipping method, distinguishing it from tube-packaged variants like the AD.

Inverter Gates Replacement Considerations

Compatible equivalents include other manufacturers' SN74LVC02 parts in SOIC-14 packages. Verify pinout compatibility and electrical characteristics such as propagation delay and output current drive before substitution.
