XR31233, XR31234, XR31235 36V Fault Tolerant, Single 3.3V CAN Bus Transceivers General Description FEATURES The XR31233, XR31234 and XR31235 are controller area network Single 3.3V operation (CAN) transceivers that conform to the ISO 11898 standard. Each 36V fault tolerance on analog bus pins Extended -25V to +25V common mode provides transmit and receive signaling rates up to 1Mbps between a operation differential CAN bus and a CAN controller. Robust ESD protection: 16kV HBM (bus pins) 8kV contact discharge (bus pins) These devices are designed with cross-wire protection, overvoltage 3kV HBM (non-bus pins) protection up to 36V, loss of ground protection, thermal shutdown Up to 1Mbps data rates protection and common-mode transient protection of 100V making 11898-2 ISO compatible them ideal for harsh environments used in industrial, automotive, GIFT/ICT compliant transportation and building automation applications. 5V tolerant LVTTL I/Os 200A low current standby mode The low power consumption of the 3.3V supply makes these CAN XR31233: Loopback mode transceivers desirable and are fully interoperable with 5V supplied XR31234: Ultra low current sleep mode transceivers on the same bus. They also offer high speed, slope 50nA typical control and low-power standby modes of operation.
