DESCRIPTION
The ISO1050 is a galvanically isolated CAN transceiver that meets or exceeds the specifications of the ISO
11898 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 4000 VPEAK. 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 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.
