ISO3080DW Datasheet

Interface ICs


The ISO3080DW , and ISO3086 are isolated full-duplex differential line drivers and receivers while the ISO3082, and ISO3088 are isolated half-duplex differential line transceivers for TIA/EIA 485/422 applications. These devices are ideal for long transmission lines since the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500 Vrms of isolation for 60s 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 near-by 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. ISO3080DW Features • Signaling Rates up to 20 Mbps• Thermal Shutdown Protection• Low Bus Capacitance – 16 pF (Typ)• 50 kV/μs Typical Transient Immunity• Fail-safe Receiver for Bus Open, Short, Idle• 3.3-V Inputs are 5-V Tolerant ISO3080DW Applications • Security Systems• Chemical Production• Factory Automation• Motor/Motion Control• HVAC and Building Automation Networks• Networked Security Stations
