The ISO1050 is a galvanically isolated CAN transceiver that meets or exceeds the specifications of the ISO

device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with

or damaging sensitive circuitry.

As a CAN transceiver, the device provides differential transmit capability to the bus and differential receive

capability to a CAN controller at signaling rates up to 1 megabit per second (Mbps). Designed for operation in

especially harsh environments, the device features cross-wire, overvoltage and loss of ground protection from

–27 V to 40 V and overtemperature shut-down, as well as a –12 V to 12 V common-mode range.

The ISO1050 is characterized for operation over the ambient temperature range of –55°C to 105°C.
