ISL32174EIBZ

ISL32174EIBZ is a QUAD, ±16.5kV ESD protected, 3V to 5.5V, low power, RS-422 transmitter for balanced communication using the RS422 standard. This driver has very low output leakage currents (±10µA), so they present a low load to the RS-422 bus. The driver (Tx) outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. The ISL32172E and ISL32272E have a common EN/EN, the ISL32174E has a two channel EN12/EN34, and the ISL32179E has a versatile combination of individual and group channel enables. Drivers on the other version is not limited, so this can achieve 10Mbps or 32Mbps data rates. Application includes telecom equipment, motor controllers/encoders, programmable logic controllers, industrial/process control networks.
