Overview

Description

These Renesas devices are ±16. 5kV IEC61000-4-2 ESD protected, 3. 0V to 5. 5V powered, quad receivers 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 ISL32173E and ISL32177E are high data rate receivers that operate at data rates up to 80Mbps. Their 8ns maximum propagation delay skew (tolerance) ensures excellent part-to-part matching. The ISL32273E, ISL32275E, and ISL32277E are reduced supply current versions 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. Versions are available with a common EN/EN (ISL32173E pinout) or a versatile individual channel enable (see Table 1). A 26% smaller footprint is available with the ISL32177E and ISL32277E 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, to levels compatible with a lower supply voltage in mixed voltage systems. Individual channel and group enable pins increase the flexibility of the ISL32177E and ISL32277E.
