The MAX3486EC/D, developed by Maxim (now Analog Devices), is a 3.3V half-duplex RS-485/RS-422 transceiver featuring low power consumption, high data rates, and strong noise immunity. It is widely used in industrial automation, building control, and embedded communication systems.

Key Features:

• Operating Voltage: 3.3V, compatible with low-power MCU systems

• Data Rate: Up to 10 Mbps

• ESD Protection: ±15 kV for enhanced reliability

• Topology: Half-duplex RS-485/RS-422

• Operating Temperature: -40°C to +85°C

• Package: SOIC-8, ideal for surface-mount assembly

Applications:
The MAX3486EC/D is commonly used in PLC control, building energy management, instrumentation, and serial communication gateways. Its robust differential signaling ensures stable data transmission even in noisy or long-distance environments.

Selection Tips:
For systems operating at 3.3V logic levels, the MAX3486EC/D is an ideal choice, eliminating the need for level shifters. For full-duplex designs, consider the MAX3488 series.

Conclusion:
With low power, high reliability, and excellent compatibility, the MAX3486EC/D remains a trusted solution for RS-485 communication systems.
