Product specication
High speed CAN transceiver
TJA1040
Note
1. All parameters are guaranteed over the virtual junction temperature range by design, but only 100% tested at 125
°C
ambient temperature for dies on wafer level, and in addition to this 100% tested at 25
°C ambient temperature for
cased products; unless specied otherwise. For bare dies, all parameters are only guaranteed with the backside of
the die connected to ground.
