The MAX3488AEGSA+ is a 3.3V powered, ±20KV ESD-protected, 20Mbps and slew-rate-limited RS485/RS422 transceiver in 8 pin SOIC package. It is a ±20KV ESD-protected RS485/422 transceiver, optimized for extended cable runs in noisy environments. It is a full-duplex transceiver. The receiver features a unit-load input impedance allowing up to 32 devices on a single bus. The 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. It features enhanced electrostatic discharge (ESD) protection. The transmitter output and receiver input are protected to ±20KV HBM ESD, ±15KV Air-Gap ESD and ±8KV contact ESD in accordance to IEC 61000-4-2.
