DESCRIPTION
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 V_RMS for ISO1050DW and 2500 V_RMS 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). 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 over-temperature shut-down, 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 105°C.
