ISO3088 隔离式 5V 全双工和半双工 RS-485 收发器

The ISO3080, 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.
