MAX3085EESA

The MAX3085EESA is designed as one kind of ±15kVESD-protected,fail-safe,high-speed (10Mbps), slew-rate-limited RS-485/RS-422 transceiver that can be used in (1)RS-422/RS-485 communications; (2)level translators; (3)transceivers for EMI-sensitive applications; (4)industrial-control local area networks. This device has a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus, and the slew rate of it is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver.

Features of the MAX3085EESA are:(1)ESD protection for RS-485 I/O Pins ±15kV, human body model; (2)true fail-safe receiver while maintaining EIA/TIA-485 compatibility; (3)enhanced slew-rate limiting facilitates error-free data transmission; (4)1na low-current shutdown mode; (5)pin-selectable full/half-duplex operation; (6)phase controls to correct for twisted-pair reversal; (7)allow up to 256 transceivers on the bus.

The absolute maximum ratings of the MAX3085EESA can be summarized as:(1)Supply Voltage (VCC): +7 V;(2)Control Input Voltage (RE, DE): -0.3 V to (VCC + 0.3 V);(3)Driver Input Voltage (DI): -0.3 V to (VCC + 0.3 V);(4)Driver Output Voltage (A, B, Y, Z): ±13 V;(5)Receiver Input Voltage (A, B): ±13 V;(6)Receiver Input Voltage, Full Duplex (A, B): ±25 V;(7)Receiver Output Voltage (RO): -0.3 V to (VCC + 0.3 V);(8)Lead Temperature (soldering, 10s): +300°C;(9)Storage Temperature Range: -65°C to +150°C;(10)Operating Temperature Range: -40°C to +85°C.

The electrical characteristics of this device can be summarized as:(1)Differential Driver Output (No Load): 5 V;(2)Differential Driver Output: 1.5 V or 2.0 V;(3)Change-in-Magnitude of Differential Output Voltage: 0.2 V;(4)Driver Common-Mode Output Voltage: 3 V;(5)Change-in-Magnitude of Common-Mode Voltage: 0.2 V;(6)Input High Voltage: 2.0 V;(7)Input Low Voltage: 0.8 V;(8)DI Input Hysteresis: 100 mV.
