Philips Semiconductors Product specification
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 specified otherwise. For bare dies, all parameters are only guaranteed with the backside of
the die connected to ground.
