6 V is the IEC 60134 Absolute Maximum Rating (AMR) for VCC and VIO (see Limiting values table). Above the AMR, irreversible changes in

characteristics, functionality or performance may occur. Returning from above AMR to the operating range, datasheet characteristics and

functionality cannot be guaranteed.

Target transceiver functionality as described in this datasheet is applicable.

Prolonged operation of the device outside the operating range may impact reliability over lifetime. Returning to the operating range, datasheet

characteristics are guaranteed provided the AMR has not been exceeded.

7.2 Fail-safe features

7.2.1 TXD dominant time-out function

A 'TXD dominant time-out' timer is started when pin TXD is set LOW. If the LOW state on

this pin persists for longer than tto(dom)TXD, the transmitter is disabled, releasing the bus

lines to recessive state. This function prevents a hardware and/or software application

failure from driving the bus lines to a permanent dominant state (blocking all network

communications). The TXD dominant time-out timer is reset when pin TXD goes HIGH.

7.2.2 Internal biasing of TXD and mode input pins

state in case one or more of these pins is left open or become floating. Pull-up resistors
