Texas Instruments ISO35
the ISO35 is an isolated full-duplex differential line driver and receiver for TIA/EIA 485/422 applications. The ISO15M and ISO35M have extended ambient temperature ratings of –55°C to 125°C while the ISO15 and ISO35 are specified over –40°C to 85°C. These devices are ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range.| Part No. | ISO35 |

DESCRIPTION
The ISO15 is an isolated half-duplex differential line transceiver while The symmetrical barrier of the device is tested to provide isolatlion of 4000 VPK per VDE and 2500 VRMS per UL and CSA between the bus-line transceiver and the logic-level interface. Any cabled I/O can be subjected to electrical noise transients from various sources.
