7 / 17 page 2003 Oct 14 7 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.
