Product Overview
The MAX3491ESD+ is a 3.3V powered, true RS485/RS422 transceiver in 14 pin NSOIC package. The device has transmission data rate up to 10Mbps. The driver is short circuit current limited and protected against excessive power dissipation by thermal shutdown circuitry that places the driver output into a high impedance state. The receiver input has a fail-safe feature that gives a logic high output if both inputs are open circuit.
- Supply voltage range from 3V to 3.6V
- Operating temperature range from -40°C to 85°C
- One driver and one receiver
- No charge pump
- Full duplex communication
- Driver/receiver enable function
- Allows up to 32 transceivers on the bus
- Interoperable with +5V logic
- Common mode input voltage range from -7V to +12V
- Low shutdown current of 2nA
