Table 8. Dynamic characteristics â¦continued
Tvj = â40 °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. Factory testing uses 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) or an EN pin (TJA1051T/E), these
inputs are connected to pin VCC.
