ISL32275EFVZ

ISL32275EFVZ is a ±16.5KV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered, quad receiver for balanced communication using the RS-485 and RS-422 standards. It has low input currents (±200µA), so it presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus. This is a reduced supply current version that operate at data rates up to 20Mbps. The receiver outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. The VL supply sets the switching points of the enable inputs and the receiver outputs’ VOH, to levels compatible with a lower supply voltage in mixed voltage systems. Application includes telecom equipment, motor controllers/encoders, programmable logic controllers, industrial/process control networks.
