NOTE:

1. RX outputs the bus state. If the bus level is below the receiver threshold (i.e., all transmitters passive), then RX will be floating (i.e., high,

considering external pull-up resistance). Otherwise, if the bus level is above the receiver threshold (i.e., at least one transmitter is active),

then RX will be low.

ABSOLUTE MAXIMUM RATINGS

According to the IEC 134 Absolute Maximum System; operation is not guaranteed under these conditions; all voltages are referenced to pin 8

(GND); positive currents flow into the IC; unless otherwise specified.
