SN74LV02ADGVR

Inverter Gates Overview

The SN74LV02ADGVR 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 compatibility, preventing backflow current when powered down. It provides ESD protection exceeding JESD 22 standards, including 2000-V human-body model and 1000-V charged-device model ratings. Latch-up performance exceeds 250 mA per JESD 17. The component is housed in a 14-pin TVSOP package.

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-14 package with tape-and-reel packaging. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure input pins are tied to valid logic levels to prevent undefined states during operation.

Inverter Gates Selection Notes

Select this component for applications requiring low drive strength to minimize output ringing and overshoot. It is suitable for bus interface designs where slow edge rates are beneficial. Verify that the 2-V to 5.5-V operating range aligns with the system's power supply architecture and voltage translation requirements.

Inverter Gates Part Context

This part belongs to the SNx4LV02A family of Low drive CMOS quadruple 2-input positive-NOR gates. The family is designed for high-speed digital logic applications requiring reliable performance across a wide voltage spectrum. The 'A' suffix indicates an enhanced version of the original LV02 specification.

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 maximum input voltage tolerance?

Inputs accept voltages up to 5.5 V at any valid VCC, allowing for direct interfacing with higher voltage logic without external level shifters.
