The ISO15 is an isolated half-duplex differential line transceiver while 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.
devices are ideal for long transmission lines because the ground loop is broken to allow for a much
larger common-mode voltage range. 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.
These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if
they are of sufficient magnitude and duration. These isolated devices can significantly increase
protection and reduce the risk of damage to expensive control circuits.
