TJA1055
Enhanced fault-tolerant CAN transceiver
V
TXD
is a rectangular signal of 50 kHz with 50 % duty cycle and slope time < 10 ns.
Termination resistors R
CAN_L
and R
CAN_H
(125
) are not connected to pin RTL or pin RTH for
testing purposes because the minimum load allowed on the CAN bus lines is 500
per
transceiver.
