MAX3485ECSA+

MAX3485ECSA+ is a ±15kV ESD-protected, +3.3V, low-power transceiver for RS-485 and RS-422 communications. It contains one driver and one receiver. The MAX3485E transmit at up to 12Mbps. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap\ Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. Driver is short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if both inputs are open circuit.

• Half duplex communication
• Supply voltage range from 3.0 to 3.6V
• Driver/ receiver enable
• 2nA low-current shutdown mode
• Interoperable with +5V Logic
• Common-mode input voltage range -7V to +12V
• Current-limiting and thermal shutdown for driver overload protection
• Operating temperature range from 0 to 70°C
• Available in 8 pin SOIC package
