Working Principles

The MAX13235EETP+ is a half-duplex RS-485/RS-422 transceiver. It enables bidirectional data communication between two devices over long distances. The driver section converts the logic-level signals into differential voltages, while the receiver section converts the differential voltages back into logic-level signals. This allows for reliable data transmission in noisy industrial environments.

Detailed Application Field Plans

The MAX13235EETP+ is commonly used in the following application fields: 1. Industrial automation systems 2. Building control systems 3. HVAC (Heating, Ventilation, and Air Conditioning) systems 4. Security and access control systems 5. Instrumentation and measurement equipment
