Texas Instruments  SN888CDR

The SN888C is a low-power RS-485 transceiver with bus-polarity correction and transient protection. Upon hot plug-in the device detects and corrects the bus polarity within the first 76 ms of bus idling. On-chip transient protection protects the device against IEC61000 ESD and EFT transients.

The SN888C is available in an SOIC-8 package. The device is characterized from –40°C to 85°C.
