Enhanced fault-tolerant CAN transceiver
[1]
All parameters are guaranteed over the virtual junction temperature range by design, but only 100 % tested at Tamb = 125 °C for dies on
wafer level, and above this for cased products 100 % tested at Tamb =25 °C, unless otherwise specied.
[2]
To guarantee a successful mode transition under all conditions, the maximum specied time must be applied.
