CA-IF4888HS
Active
RS-485/RS-422 Transceiver
The CA-IF4888HS is a low-power RS-485 transceiver with automatic bus-polarity correction. Upon hot plug-in, the device detects and corrects the bus polarity within the first 114ms (tFS-max) of bus idling. This device can extend the common mode voltage range to ±15V, and the fault protection range to ±30V. Therefore, this device is suitable for long cable applications. The bus pins are robust to electrostatic discharge (ESD) events, with high levels of protection to human-body model (HBM), and contact discharge specifications.
The CA-IF4888HS is available in a narrow-body SOIC8 package, which is suitable for space-constrained applications. This device is specified over ambient free-air temperature range of –40°C to 125°C.
