All parameters are guaranteed over the virtual junction temperature range by design. Factory testing uses correlated test conditions to
cover the specified temperature and power supply voltage ranges.
Not applicable to the low slope versions (TJA1028T/xxx/10 and TJA1028TK/xxx/10) of the TJA1028.
Bus load conditions are: C
For V
Not tested in production; guaranteed by design.
