1 X31233, X31234, X31235 ±36V Fault Tolerant, Single 3.3V CAN Bus Transceivers General escription The X31233, X31234 and X31235 are controller area network (CAN) transceivers that conform to the ISO standard. Each provides transmit and receive signaling rates up to 1Mbps between a differential CAN bus and a CAN controller. These devices are designed with cross-wire protection, overvoltage protection up to ±36V, loss of ground protection, thermal shutdown protection and common-mode transient protection of ±100V making them ideal for harsh environments used in industrial, automotive, transportation and building automation applications. The low power consumption of the 3.3V supply makes these CAN transceivers desirable and are fully interoperable with 5V supplied transceivers on the same bus. They also offer high speed, slope control and low-power standby modes of operation.
