3 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 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 –12V to 12V common-mode

range.

The ISO1050 is characterized for operation over the

ambient temperature range of –55°C to 105°C.
