High-speed CAN transceiver
[4] Vcm(CAN) is the common mode voltage of CANH and CANL.

Table 7. Dynamic characteristics
Tvj = −40 °C to +150 °C; VCC = 4.5 V to 5.5 V; VIO = 2.8 V to 5.5 V[1]; RL = 60 Ω unless specified otherwise. All voltages are
defined with respect to ground. Positive currents flow into the IC.[2]

[1] Only TJA1051T/3 and TJA1051TK/3 have a VIO pin. In transceivers without a VIO pin, the VIO input is internally connected to VCC.
[2] All parameters are guaranteed over the virtual junction temperature range by design. Products are 100 % tested at 125 °C ambient
temperature (wafer level pretesting), and 100 % tested at 25 °C ambient temperature (final testing). Both pretesting and final testing use
correlated test conditions to cover the specified temperature and power supply voltage range.

(1) For versions with a VIO pin (TJA1051T/3 and TJA1051TK/3), the VIO input is connected to pin VCC.
