SN74LV02APW

Inverter Gates Overview

The SN74LV02APW is a quadruple 2-input positive-NOR gate from the Texas Instruments SNx4LV02A series, housed in a 14-pin TSSOP package. 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 an Ioff circuit that disables outputs during partial power-down mode to prevent back-driving currents. It provides latch-up performance exceeding 250 mA per JESD 17 and includes ESD protection rated at ±2000 V for the charged-device model.

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 JESD 17 standards

Inverter Gates Applications

• Smartphone handset logic
• Network switch interfaces
• Health and fitness wearable devices
• Power infrastructure systems

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-14 package variant required for your design. Confirm the active status of this part number against the latest TI Package Option Addendum, as manufacturing statuses can change. Ensure compatibility with your board assembly process regarding moisture sensitivity levels and reflow temperature profiles specified for surface-mount components.

Inverter Gates Selection Notes

Select this component when a low-drive CMOS NOR gate is needed for bus interface applications where output ringing must be minimized. The slow edge rates help reduce overshoot and undershoot. Verify that input voltages do not exceed 5.5 V, as they are overvoltage tolerant regardless of the VCC level. Ensure unused inputs are tied to VCC or GND to maintain defined operational states.

Inverter Gates Part Context

This device belongs to the SNx4LV02A family of quadruple 2-input positive-NOR gates designed for 2-V to 5.5-V operation. The family utilizes Low drive CMOS technology to manage signal integrity in high-speed digital circuits. The SN74LV02A variant specifically targets commercial temperature ranges and standard industrial applications compared to its military-grade counterparts.

Inverter Gates FAQ

How does the Ioff feature function?

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

What is the maximum input voltage tolerance?

Inputs accept voltages up to 5.5 V at any valid VCC, allowing for down voltage translation without external level shifters.
