FAULT CONDITIONS
The ADN4696E/ADN4697E contain short-circuit current
protection that protects the part under fault conditions in the
case of short circuits on the bus. This limits the current in a
fault condition to 24 mA at the transmitter outputs for short-
circuit faults between 1 V and +3.4 V. Any network fault must
be cleared to avoid data transmission errors and ensure reliable
operation of the data network and any devices connected to the
network.
RECEIVER INPUT THRESHOLDS/FAIL-SAFE
Type 2 receivers (ADN4696E/ADN4697E) have an open circuit
and bus-idle fail-safe, as well as protection against short circuits.
The input threshold is offset by 100 mV so that a logic high is
present on the receiver output when the bus is idle or when the
receiver inputs are open.
The different receiver thresholds are illustrated in Figure 36.
