Présentation

Description

The MAX3490ESA+T is a 3.3V, low-power RS-485/RS-422 transceiver from Maxim Integrated (now part of Analog Devices). It features half-duplex communication, supporting data rates up to 10Mbps.
Key features:
- Low power consumption (0.3mA in shutdown, 2.5mA in standby).
- ±15kV ESD protection on bus pins for robustness.
- 1/8-unit load allows up to 256 nodes on a bus.
- Thermal shutdown and short-circuit protection.
Applications include industrial automation, HVAC systems, and long-distance data transmission. The SOIC-8 package (ESA+T) ensures compact PCB integration.
For full details, refer to the datasheet on Analog Devices' website.
