MAX3089CSD+

The MAX3089CSD+ is a fail-safe, high speed (10Mbps), RS485/RS422 transceiver in 14 pin NSOIC package. The fail-safe circuitry in this device features a logic high receiver output when receiver inputs are open or shorted, it means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). This device has selectable slew rate between 115Kbps, 500Kbps and 10Mbps by driving a selector pin with a single three state driver. It has a 1/8 unit load receiver input impedance that allows up to 256 transceivers on the bus.

• Supply voltage range from 4.75V to 5.25V
• Operating temperature range from 0°C to 70°C
• Quiescent current is 375µA
• Selectable between half duplex & full duplex communication
• Independent programmable receiver & transmitter output phase via separate pins
• Low power shutdown mode with 0.001µA supply current
• Features receiver/driver enable function
