MAX3085EESA is a 3.

The MAX3085EESA is a 3.3V-powered, ±15kV ESD-protected, 20Mbps, half-duplex RS-485/RS-422 transceiver manufactured by Maxim Integrated (now part of Analog Devices).

Key Specifications:

  • Supply Voltage: 3.3V ±10%
  • Data Rate: Up to 20Mbps
  • ESD Protection: ±15kV (Human Body Model)
  • Operating Temperature Range: -40°C to +85°C
  • Package: 8-pin SOIC (MAX3085EESA)
  • Number of Drivers/Receivers: 1 Driver, 1 Receiver
  • Half-Duplex Communication
  • Low Power Consumption:
  • Shutdown Current: 1µA (max)
  • Quiescent Current: 900µA (max)

Features:

  • Enhanced ESD Protection: Protects against ±15kV on bus pins (IEC 61000-4-2 Air-Gap Discharge).
  • Fail-Safe Receiver: Ensures logic-high output when inputs are open, shorted, or terminated but not driven.
  • Hot-Swap Input Structure: Eliminates false transitions during power-up/down.
  • Slew-Rate Limited for Reduced EMI (MAX3085EESA+ only)
  • Compatible with RS-485 and RS-422 Standards
  • Short-Circuit Protection on Driver Outputs
  • Thermal Shutdown Protection

Applications:

  • Industrial control systems
  • Building automation
  • HVAC systems
  • Network equipment
  • Point-of-sale terminals

This transceiver is designed for robust communication in noisy environments while maintaining low power consumption.
