Product Details

The MAX33045E/MAX33046E is a half-duplex RS-485/422 transceiver that operates at either 3.3V or 5.0V supply rail for ease of design. Both devices feature enhanced protection for applications in harsh environments. All driver outputs and receiver inputs are protected with both high-fault and high-ESD (electrostatic discharge) protection.

The A/B lines have up to ±25V fault protection for accidental shorts with local power supplies and ±40kV ESD (Human Body Model) HBM protection. They are also rated up to ±15kV Air-Gap Discharge and ±10kV Contact Discharge per IEC 61000-4-2. Both features ensure robust protection in harsh industrial environments. Drivers are short-circuit current limited and protected against excessive power dissipation by thermal-shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a true fail-safe feature that guarantees a logic-high output if both inputs are open or short circuited.

The MAX33045E is rated for a 500kbps (min) data rate, and the MAX33046E is rated for a 20Mbps data rate.

Both devices are packaged in an 8-pin SOIC with an operating ambient temperature from -40°C to +125°C.
