ISL32273EIVZ-T

These Intersil devices are ±16.5kV IEC61000-4-2 ESD protected,3.0V to 5.5V powered, QUAD receivers for balancedcommunication using the RS-485 and RS-422 standards. Eachreceiver has low input currents (±200µA), so it presents a 1/4unit load to the RS-485 bus, and allows up to 128 receivers onthe bus. The ISL32173E, ISL32175E, ISL32177E are high data ratereceivers that operate at data rates up to 80Mbps. Their 8nsmaximum propagation delay skew (tolerance) guaranteesexcellent part-to-part matching. The ISL32273E, ISL32275E,ISL32277E are reduced supply current versions that operate atdata rates up to 20Mbps.
