RS-485

Maxim's RS-485 solutions for PIN Pad (Kiosk) terminals provide advanced capabilities for best the signal integrity and most robust systems.

Up to ±15kV ESD Protection (per Human Body Model)
Slew-Rate Limiting Minimizes Reflections and Allows Longer Transmission Lengths
Hot-Swap Capability Eliminates Erroneous Data
True Fail-Safe for Fault Detection
1/8 Unit Load Minimizes Voltage Drops Across the Bus and Allows Longer Transmission Lengths
3.3V Single-Supply Operation (MAX3070E-MAX3079E only)
