The MAX14840EATA+T is a 3.3V, 40Mbps, RS485 half duplex transceiver in 8 pin TDFN package. This transceiver is optimized for high speeds over extended cable runs while maximizing tolerance to noise. The transmitter outputs and receiver inputs are protected ±15KV using IEC 1000-4-2 air gap discharge, ±8KV using IEC 1000-4-2 contact discharge and ±15KV using human body model. The MAX14840E features symmetrical fail-safe and larger receiver hysteresis providing improved noise rejection and improved recovered signals in high-speed and long cable applications. Typical applications include motion controllers, fieldbus networks, industrial control systems, backplane buses and HVAC networks.
