ISL32173E

These Intersil 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, ISL32175E, ISL32177E are 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 ISL32273E, ISL32275E, ISL32277E are 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 down. Versions are available with a common EN/EN (173 pinout), a two channel EN12/EN34 (175 pinout), or a versatile individual channel enable.

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 ISL32177E and ISL32277Es flexibility.
