Product Summary
The MAX3082ESA is a high-speed transceiver for RS-485/RS-422 communication contain one driver and one receiver. The device features fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The applications of the MAX3082ESA include RS-422/RS-485 Communications, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks.
Parametrics
MAX3082ESA 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
MAX3082ESA features: (1)True Fail-Safe Receiver While Maintaining EIA/TIA-485 Compatibility; (2)Enhanced Slew-Rate Limiting Facilitates Error-Free Data Transmission (MAX3080–MAX3085/MAX3089); (3)1nA Low-Current Shutdown Mode (except MAX3081/MAX3084/MAX3087); (4)Pin-Selectable Full/Half-Duplex Operation (MAX3089); (5)Phase Controls to Correct for Twisted-Pair Reversal (MAX3089); (6)Allow Up to 256 Transceivers on the Bus.
