The CA-IF4888 half-duplex ±30kV ESD-protected RS-485 transceiver features integrated automatic polarity correction to ensure that miswired A and B lines are autonomously corrected, simplifying equipment and network installation. Upon hot plug-in, the CA-IF4888 detects and corrects the bus polarity within the first 76 ms of bus idling. This device has ±30V fault protection for overvoltage conditions on the communication bus lines that ensure robust protection on the bus. It also features ±15V of common-mode range (CMR), making them ideal for electrically noisy environments where different systems have shifting ground levels relative to each other and long distance transmission.
The CA-IF4888 device is specified over the -40°C to +125°C operating temperature range and is available in SOIC8 package.
