MAX485ESA+

The MAX485ESA+ is one member of the MAX485 family which is designed as the low-power, slew-rate-limited RS-485/RS-422 transceiver that can be used in (1)low-power RS-485 transceivers; (2)low-power RS-422 transceivers; (3)level translators; (4)transceivers for EMI-sensitive applications; (5)industrial-control local area networks. And this device features quarter-unit-load receiver input impedance, allowing up to 128 MAX487 / MAX1487 transceivers on the bus.

Features of the MAX485ESA+ are:(1)+3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited, True RS-485/RS-422 Transceiver;(2)Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422 Transceiver;(3)Applications MAX3030EMAX3033E: ±15kV ESD-Protected, +3.3V, Quad RS-422 Transmitter.

The absolute maximum ratings of the MAX485ESA+ can be summarized as:(1)Supply Voltage (VCC): 12 V;(2)Control Input Voltage (RE, DE): -0.5V to (VCC + 0.5V);(3)Driver Input Voltage (DI): -0.5V to (VCC + 0.5V);(4)Driver Output Voltage (A, B): -8V to +12.5V;(5)Receiver Input Voltage (A, B): -8V to +12.5V;(6)Receiver Output Voltage (RO): -0.5V to (VCC +0.5V);(7)Lead Temperature (soldering, 10sec): +300°C;(8)Storage Temperature Range: -65°C to +160°C;(9)Operating Temperature Range: -40°C to +85°C.

The electrical characteristics of the MAX485ESA+ can be summarized as:(1)Differential Driver Output (no load): 5 V;(2)Input High Voltage: 2.0 V;(3)Input Low Voltage: 0.8 V;(4)Input Current: ±2 A;(5)Receiver Input Hysteresis: 70 mV;(6)Receiver Output High Voltage: 3.5 V;(7)Receiver Differential Threshold Voltage: -0.2 to 0.2 V.
