NBA3N20XS, Multi-Point, M-LVDS Drivers and Receive

ON Semiconductor’s NBA3N20xS devices are 3.3 V supply differential, multi-point low-voltage (M-LVDS) line drivers and receivers for automotive applications. The NBA3N200S and NBA3N201S offer the Type-1 receiver threshold at 0.0 V. Type-1 receivers 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. 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.  The NBA3N206S offers the Type 2 receiver threshold at 0.1 V. Type-2 receivers 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 and include an offset threshold to provide a detectable voltage under open-circuit, idle-bus, and other faults conditions. The NBA3N20xS family of devices supports Simplex bus configurations or Half Duplex bus configurations.
