                      Product Overview

                      The MAX491ESD+T is a low power RS485/RS422 transceiver in 14 pin NSOIC package. It contains one driver and one receiver. The slew rate is not limited allowing it to transmit up to 2.5Mbps. The driver is short circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state. It features fail-safe circuitry which has a logic high receiver output when the receiver input is open.
