Description
MAX3295AUT+T is an automotive-grade differential transceiver from Maxim. It combines a driver and a receiver to connect a microcontroller to an RS-485/RS-422 multi-point bus.
Key points:
- Interfaces: A/B bus lines on the differential side; DI (driver input), RO (receiver output) on the MCU side; DE/RE or similar control pins to enable driver and receiver.
- Features: low-power operation, failsafe receiver (bus idle/shorts produce a defined logic level), built-in protection (ESD/overload), single-supply compatibility (typical 3.3V or 5V), suitable for harsh environments.
- Packaging: AUT indicates automotive-grade device with extended temperature range; +T denotes tape-and-reel packaging.
- Applications: automotive networks, industrial RS-485/RS-422 systems requiring durable, wide-temperature operation.
How to use: mount A/B to the differential bus, drive DI to send data, read RO for received data, and manage DE/RE to control transmission. Include proper line termination and biasing per the bus topology.
