Texas Instruments SN888C Bus-Polarity Correcting RS-485 Transceiver with IEC-ESD Protection SN888CD

The SN888C is a low-power RS-485 transceiver designed for bus-polarity correction and transient protection, suitable for applications such as E-meters. It operates at data rates ranging from 300 bps to 250 kbps and supports configurations with failsafe resistors, either alone or in conjunction with termination resistors. The device can accommodate up to 256 nodes on a bus and features built-in protection against electrostatic discharge (ESD) with ratings of ¬±16 kV HBM and ¬±12 kV IEC61000-4-2 contact discharge. The SN888C is housed in an SOIC-8 package, ensuring backward compatibility, and is characterized for operation within a temperature range of -40¬8C to 85¬8C. The transceiver's ability to correct bus polarity within 76 ms upon hot plug-in enhances its reliability in dynamic environments. This product is particularly relevant for engineers looking for robust communication solutions in industrial applications.
