SN74LV02ADR

Inverter Gates Overview

The SN74LV02ADR 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 a maximum propagation delay of 6.5 ns at 5 V and includes Ioff circuitry for partial power-down mode support. It provides latch-up performance exceeding 250 mA per JESD 17 and offers ESD protection up to 2000 V via the charged-device model.

Inverter Gates Procurement Notes

Verify the specific package type, as the SN74LV02A family utilizes multiple form factors including SOIC, SSOP, TSSOP, TVSOP, SOP, and VQFN. Confirm that the ordering suffix matches the required physical dimensions and pin pitch for your PCB layout. Ensure compatibility with the intended operating temperature range and verify RoHS compliance status before finalizing procurement.

Inverter Gates Selection Notes

Select this component when low drive strength is required to minimize output ringing and overshoot in bus interface applications. The wide input voltage tolerance allows direct interfacing between systems operating at different logic levels without external level shifters. Consider the thermal resistance values associated with the chosen package style during high-density board designs.

Inverter Gates Part Context

This part belongs to the SNx4LV02A family of Low Voltage CMOS logic devices. These components are designed for general-purpose digital logic functions requiring robust performance across varying supply voltages. The SN74LV02A variant specifically targets commercial temperature ranges, distinguishing it from the SN54LV02A industrial counterpart.

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 scenarios.

What is the maximum input voltage tolerance?

Inputs accept voltages up to 5.5 V regardless of the valid VCC level, facilitating down voltage translation.
