Description
CA-IF4905S RS-485 Transceiver
The CA-IF4905S is the high-performance half-duplex RS-485 transceiver which could be used in harsh industrial and home-appliance environments. The bus pins could withstand high-level ESD events to protect internal circuit without damage. This device has ±65V fault protection on bus pins, and the common-mode range (CMR) could be extended to ±40V when VCC ranges from 4.5V to 5.5V, which is suitable for long-cable communication applications. Each device contains one driver and one receiver, supporting the power supply range from 3V to 5.5V.
The CA-IF4905S features slew-rate-limited driver for low EMI and date rates up to 500kbps. This device integrates failsafe circuit to guarantee a logical high on the receiver output when the bus inputs are open, short or on idle state. This device features a 1/8 unit load input impedance, allowing up to 256 transceivers on a bus.
The CA-IF4905S devices are packaged in narrow body, 8-pin SOIC packages and specified over ambient free-air temperature range of –40°C to 125°C.
