SN74LV02AD

Inverter Gates Overview

The SN74LV02AD is a quadruple 2-input positive-NOR gate from the Texas Instruments SNx4LV02A series. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features Ioff circuitry for partial power-down mode support, preventing backflow current when powered down. It provides latch-up performance exceeding 250 mA per JESD 17 and includes ESD protection ratings of ±1500 V (HBM) and ±2000 V (CDM). The maximum propagation delay is 6.5 ns at 5 V.

Inverter Gates Feature Summary

• Supports mixed-mode voltage operation across all ports
• Enables live insertion via Ioff partial power-down capability
• Provides robust latch-up protection exceeding 250 mA

Inverter Gates Applications

• Smartphone handset logic
• Network switch interfaces

• Power infrastructure systems

Inverter Gates Procurement Notes

Verify the specific package type and status before procurement. The SN74LV02AD designation corresponds to the SOIC-14 package. Check the manufacturer's orderable addendum for current production status, as this specific suffix may be obsolete or restricted. Confirm RoHS compliance and lead finish details directly with the supplier or official documentation prior to ordering.

Inverter Gates Selection Notes

Select this component for applications requiring low drive CMOS characteristics to minimize output ringing and overshoot. It is suitable for bus interface designs where slow edge rates are beneficial. Ensure inputs do not float; connect unused inputs to VCC or GND. Verify that load currents remain within the 25 mA per output limit to prevent exceeding maximum drive capabilities.

Inverter Gates Part Context

This part belongs to the SNx4LV02A family of quadruple 2-input positive-NOR gates. The family is designed for 2-V to 5.5-V operation and utilizes CMOS technology. Other available packages in this family include SSOP, TSSOP, SOP, TVSOP, and VQFN variants, offering flexibility for different board space and thermal requirements.

Inverter Gates FAQ

How does the Ioff feature function?

The Ioff circuitry disables outputs when VCC is 0 V, preventing damaging current backflow through the device during partial power-down scenarios.

What is the input voltage tolerance?

Inputs accept voltages up to 5.5 V regardless of the valid VCC level, allowing for direct down-voltage translation without external level shifters.
