Fault-tolerant CAN transceiver
Termination resistors R1 (100 ) are not connected to pin RTH or pin RTL for testing purposes because the minimum load allowed on
the CAN bus lines is 500
The capacitive bus load of 10 nF is split into 3 equal capacitors (3.3 nF) to simulate the bus cable.
The waveforms of the applied transients on pins CANH and CANL will be in accordance with ISO 7637 part 1: test pulses 1, 2, 3a and 3b.
