The MAX3058/MAX3059 interface between the controller area network (CAN) protocol controller and the physical wires of the bus lines in a CAN. They are primarily intended for printer and telecom backplane applications requiring data rates up to 1Mbps. These devices provide differential transmit capability to the bus and differential receive capability to the CAN controller. The MAX3058ASA output common-mode range is from -7V to +12V. The MAX3059 output common-mode range is from 0V to VCC. The MAX3059 contains an internal switch termination resistor that makes it ideal for JetLink applications. The MAX3058ASA features four different modes of operation: high speed, slope control, standby, and shutdown. The MAX3059 features three different modes of operation: high speed, slope control, and shutdown. High-speed mode allows data rates up to 1Mbps. In slope-control mode, the slew rate may be optimized for data rates up to 500kbps, so the effects of EMI are reduced, and unshielded twisted or parallel cable can be used. In standby mode, the transmitters are shut off and the receivers are put into low-current mode. In shutdown mode, the transmitter and receiver are switched off. The MAX3058/MAX3059 are available in an 8-pin SO package and are specified over the -40°C to +125°C temperature range.
