General Description

The MAX3050 and MAX3057 interface between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). They are primarily intended for systems requiring data rates up to 2Mbps and feature ±80V fault protection against shorts in highvoltage power buses. They provide differential transmit capability to the bus and differential receive capability to the CAN controller.
