Texas Instruments  ISO1050DUBR

The ISO1050 is a galvanically isolated CAN transceiver that meets the specifications ofthe ISO11898-2 standard. The device has the logic input and output buffers separated by a siliconoxide (SiO2) insulation barrier that provides galvanic isolation of up to5000 VRMS forISO1050DW and 2500 VRMS for ISO1050DUB. Used inconjunction with isolated power supplies, the device prevents noise currents on a data bus or othercircuits 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 anddifferential 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 featurescross-wire, overvoltage and loss of ground protection from –27 V to 40 V and overtemperatureshutdown, 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 to105°C.
