MAX3058/MAX3059 19-2939 Rev 1 9/03 5V, 1Mbps, Low Supply Current CAN Transceivers General Description Features The MAX3058/MAX3059 interface between the con- Four Operating Modes troller area network (CAN) protocol controller and the High-Speed Operation Up to 1Mbps physical wires of the bus lines in a CAN. They are pri- Slope-Control Mode to Reduce EMI (40kbps to marily intended for printer and telecom backplane appli- 500kbps) cations requiring data rates up to 1Mbps. These Low-Current Shutdown Mode devices provide differential transmit capability to the bus Standby Mode (MAX3058 Only) and differential receive capability to the CAN controller. Thermal Shutdown The MAX3058 output common-mode range is from -7V to +12V. The MAX3059 output common-mode range is Current Limiting from 0V to V . The MAX3059 contains an internal CC ESD Protection switch termination resistor that makes it ideal for JetLink applications. 12kV Human Body Model The MAX3058 features four different modes of opera- tion: high speed, slope control, standby, and shutdown. The MAX3059 features three different modes of opera- tion: high speed, slope control, and shutdown. High- Ordering Information speed mode allows data rates up to 1Mbps. In PART TEMP RANGE PIN-PACKAGE slope-control mode, the slew rate may be optimized for data rates up to 500kbps, so the effects of EMI are MAX3058ASA -40C to +125C 8 SO reduced, and unshielded twisted or parallel cable can MAX3059ASA -40C to +125C 8 SO 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. Selector Guide The MAX3058/MAX3059 are available in an 8-pin SO package and are specified over the -40C to +125C TERMINATION temperature range.
