Philips Semiconductors Product specification
High speed CAN transceiver TJA1050
Notes
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.
2. For bare die, all parameters are only guaranteed if the backside of the bare die is connected to ground.
