Product Summary
The MAX3085 high-speed transceiver for RS-485/RS-422 communication contains one driver and one receiver. The MAX3085 features fail-safe circuitry, which guarantees a logic-high receiver output when the receiver input is open or shorted. The MAX3085 features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3085 offers higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The applications of MAX3085 are RS-422/RS-485 Communications, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks.
Parametrics
MAX3085 absolute maximum ratings: (1)Supply Voltage (VCC) +7V; (2)Control Input Voltage (RE, DE) -0.3V to (VCC + 0.3V); (3)Special Input Voltage (H/F, SRL, TXP, RXP) -0.3V to (VCC + 0.3V); (4)Driver Input Voltage (DI) -0.3V to (VCC + 0.3V); (5)Driver Output Voltage (A, B, Y, Z) ±13V; (6)Receiver Input Voltage (A, B) ±13V; (7)Receiver Input Voltage, Full Duplex (A, B) ±25V; (8)Receiver Output Voltage (RO) -0.3V to (VCC + 0.3V).
Features
