ISL32275EFVZ-T

This device is ±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. Each receiver 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. The ISL32175E is high data rate receivers that operate at data rates up to 80Mbps. Their 8ns maximum propagation delay skew (tolerance) guarantees excellent part-to-part matching. The ISL32275E is reduced supply current versions that operate at data rates up to 20Mbps. Receiver outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. Versions are available with a common EN/EN (ISL32175E pinout). 26% smaller footprint is available with the ISL32175E QFN packages and these two devices also feature a logic supply pin (VL). The VL supply sets the switching points of the enable inputs and the receiver outputs’ VOH,
