Overview

The NB3N401S is a 3.3 V supply Quad Multipoint Low Voltage Differential Signals (M−LVDS) line drivers and receivers. The device is TIA/EIA−899 compliant. The device offers the Type 1 receiver threshold at 0.0 V and the Type 2 receiver threshold at 0.1 V. The NB3N401S supports four independent Half Duplex bus configurations. Each of the four sections has Pin (SEL) for selection of Type−1 and Type−2 receivers that detect the bus state with as little as 50 mV of differential input voltage over a common mode voltage range of −1 V to 3.4 V. The Type−1 receivers have near zero thresholds (±50 mV)and exhibit 25 mV of differential input voltage hysteresis to prevent output oscillations with slowly changing signals or loss of input. Type−2 receivers include an offset threshold to provide a detectable voltage under open-circuit, idle-bus, and other faults conditions. The NB3N401S is offered in a 48 Pin 7 mm x 7 mm x 0.9 mm QFN package.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
