TJA1051
High-speed CAN transceiver
11. Dynamic characteristics
[1] Only TJA1051T/3 and TJA1051TK/3 have a V
IO
pin. In transceivers without a V
IO
pin, the V
IO
input is internally connected to V
CC
.
[2] All parameters are guaranteed over the virtual junction temperature range by design. Factory testing uses correlated test conditions to
cover the specified temperature and power supply voltage range.
