CA-IS2082B

CA-IS2082B is an isolated half-duplex RS-485 transceiver from Chipanalog in SSOP-16 — note the interface: this is an RS-485 device, not a CAN transceiver, for fieldbus nodes in motor drives, inverters and industrial automation where the bus must survive ground-potential differences. It integrates 3.0 kVrms galvanic isolation with data rates up to 20 Mbps and a 1/8-unit load that allows up to 256 nodes on one bus, while ±100 kV/µs typical common-mode transient immunity keeps data intact through fast switching noise — one package replaces a standard RS-485 transceiver plus a separate digital isolator. Per the current datasheet (v1.04), the logic side runs from 2.375 V to 5.5 V and the bus side from 3.0 V to 5.5 V, easing mixed-voltage designs; the device is rated -40 °C to +125 °C and carries UL 1577, VDE, CSA and CQC safety certifications. Selection advice: half-duplex suits two-wire multidrop buses — for four-wire full-duplex segments choose a full-duplex isolated transceiver instead, and budget an isolated supply for the bus side, since this part isolates the signal path only.
