MAX3079EESD+

MAX3079EESD+ is a +3.3V, ±15KV ESD-protected, fail-safe, hot-swap, RS-485 transceiver that features one driver and one receiver. This device includes fail-safe circuitry, guaranteeing a logic high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if transmitter on a terminated bus is disabled (high impedance). The device includes a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion. Suitable for lighting systems, industrial control, telecom, security systems, instrumentation applications.

• Protection for robust performance: ±15kV human body model ESD on I/O pins
• True fail-safe receiver while maintaining EIA/TIA-485 compatibility
• Enhanced slew-rate-limiting facilitates error free data transmission
• Hot-swap input structure on DE and (active low)RE
• Flexible feature set for ease of design: pin-selectable full/half-duplex operation
• Allows up to 256 transceivers on the bus
• Slew rate is pin-selectable for 250Kbps, 500Kbps and 16Mbps
• Temperature range from -40°C to +85°C
• 14 pin SO package
