TJA1051
High-speed CAN transceiver
[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.
[3] Only TJA1051T/E has an EN pin.
[4] Maximum value assumes V
CC
<V
IO
; if V
CC
>V
IO
, the maximum value will be V
CC
+ 0.3 V.
[5] Not tested in production; guaranteed by design.
