Présentation
Description
Key features include:
- Low power consumption (0.3mA in shutdown mode).
- ±15kV ESD protection on bus pins for robustness.
- Driver/receiver enable control for bus management.
- Thermal shutdown to prevent damage.
The MAX3490ESA comes in an 8-pin SOIC package and operates over an extended industrial temperature range (-40°C to +85°C). It is ideal for industrial automation, HVAC systems, and long-distance communication where noise immunity is critical.
For full-duplex applications, consider the MAX3491.
