ISO15
- Meets or exceeds TIA/EIA RS-485 requirements
- 1/8 unit load – Up to 256 nodes on a bus
- Signaling rates up to 1 Mbps
- Thermal shutdown protection
- Low bus capacitance – 16 pF (typical)
- 50 kV/µs typical transient immunity
- Fail-safe receiver for bus open, short, idle
- 3.3-V inputs are 5-V tolerant
- Safety and regulatory approvals
- 4000-V PK V IOTM, 560-V PK V IORM per DIN EN IEC 60747-17 (VDE 0884-17)
- 2500 V RMS isolation rating per UL 1577
- 2500 V RMS isolation rating per CSA 62368-1.
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.
These 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 V PK per VDE and 2500 V RMS 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.
