All parameters are guaranteed by design over the virtual junction temperature range. Products are 100 % tested at 125 C ambient
temperature on wafer level (pre-testing). Cased products are 100 % tested at 25 C ambient temperature (final testing). Both pre-testing
and final testing use correlated test conditions to cover the specified temperature and power supply voltage range.
Not applicable for the /10 version of the TJA1021.

Dynamic characteristics
> 18 V the LIN transmitter might be suppressed. If TXD is HIGH then the LIN transmitter output is recessive.
