TJA1049
High-speed CAN transceiver with Standby mode
[1] Only TJA1049T/3 and TJA1049TK/3 have a V
IO
pin; in the TJA1049T and TJA1049TK, 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.
[3] See Figure 6
.
[4] Minimum value of 0.8 ms required according to SAE J2284; 0.3 ms is allowed according to ISO11898-2:2016 for legacy devices.
