نظرة عامة على المنتج
The ISO3088DWR is a Texas Instruments 20-Mbps, half-duplex, 2.5-kVrms isolated RS-485 and RS-422 transceiver. It features integrated galvanic isolation between the bus-side transceiver and the logic-side interface, rated at 2500 V RMS per UL 1577 and 4000 V PK basic insulation per DIN EN IEC 60747-17. The device is available in a 16-pin SOIC (DW) package and operates over a temperature range of -40°C to +85°C.
