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.
