MAX3485AEASA+

The MAX3485AEASA+ is a 3.3V powered, ±20KV ESD protected, 20Mbps and slew rate limited RS485/RS422 transceiver in 8 pin NSOIC package. This is a half duplex transceiver optimized for extended cable runs in noisy environments. All receiver features an unit load input impedance allowing up to 32 devices on a single bus. Transceiver includes a fail-safe receiver ensuring that the receiver output (RO) is high when inputs are shorted, open or connected to a tri-state bus. Transmitter outputs and receiver inputs are protected to ±20KV HBM ESD, ±15KV air-gap ESD and ±8KV contact ESD in accordance to IEC 61000-4-2. It is used in industrial control local area networks, transceivers for EMI-sensitive applications and telecommunications.

• Supply voltage range from 3V to 3.6V
• Supply current of 4mA (max) at DE = VCC, RE (complementary) = GND, no load
• Integrated protection increases robustness
• Short circuit protected outputs
• Operating temperature range from -40°C to +125°C
• True fail-safe receiver prevents false transition on receiver input short or open events
• Hot swap capability eliminates false transitions during power-up or hot insertion
• Allows up to 128 transceivers on the bus
