CAN TRANSCEIVER
TECHNICAL DATA
ILA82C251
The ILA82C251 is the interface between the CAN protocol
controller and the physical bus. The device provides
differential transmit capability to the bus and differential
receive capability to the CAN controller. The IC is intended
for automotive electronic applications
