The MAX3057ASA+T is a ±80V fault-protected, 2Mbps, low supply current CAN transceiver in 8 pin NSOIC package. It interfaces between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). It is primarily intended for systems requiring data rates up to 2Mbps and feature ±80V fault protection against shorts in high voltage power buses. It provides differential transmit capability to bus and differential receive capability to CAN controller. It has four modes of operation namely high speed, slope control, standby and shutdown. High speed mode allows data rates up to 2Mbps. In slope-control mode data rates are 40Kbps to 500Kbps, so the effects of EMI are reduced and unshielded twisted or parallel cable can be used. In standby mode transmitters are shut off and the receivers are put into low-current mode. In shutdown mode transmitter and receiver are switched off. This IC is used in telecom industry for 72V systems.
