The ISO1050 is a galvanically isolated CAN transceiver that meets the specifications of
the ISO11898-2 standard. The device has the logic input and output buffers separated by a silicon
oxide (SiO2) insulation barrier that provides galvanic isolation of up to
5000 VRMS for
ISO1050DW and 2500 VRMS for ISO1050DUB. Used in
conjunction with isolated power supplies, the 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). The device is designed for operation in especially harsh environments, and it features
cross-wire, overvoltage and loss of ground protection from –27 V to 40 V and overtemperature
shutdown, as well as –12-V to 12-V common-mode range.
The ISO1050 is characterized for operation over the ambient temperature range of –55°C to
