XR31233, XR31234, XR31235
±36V Fault Tolerant, Single 3.3V
CAN Bus Transceivers
General Description
The XR31233, XR31234 and XR31235 are controller area network
(CAN) transceivers that conform to the ISO 11898 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.
