RS-485 и RS-422 MAX13089EASD+

Приемопередатчик RS422 , RS485, 4.5В-5.5В питание, 1 драйвер, NSOIC-14

The MAX13089EASD+ is a ±15KV ESD protected, fail-safe, hot swap, +5V RS485/RS422 transceiver in 14 pin NSOIC package. The fail-safe circuitry in this device features a logic high receiver output when receiver input is open or shorted. The receiver outputs a logic high if all transmitters on a terminated bus are disabled (high impedance) and a hot swap capability to eliminate false transitions on the bus during power-up or hot insertion. This device features slew rate which is pin selectable for 250Kbps, 500Kbps and 16Mbps and has independently programmable receiver and transmitter output phase through separate pins. It has a 1/8 unit load receiver input impedance which allows up to 256 transceivers on the bus.

• Supply voltage range from 4.5V to 5.5V
• Automotive temperature range from -40°C to 125°C
• One driver and one receiver
• Selectable for half duplex or full duplex operation
• True fail-safe receiver while maintaining EIA
• TIA-485 compatibility
• Hot swap input structures on DE and RE(complimentary)
• Phase controls to correct for twisted pair reversal
