DATASHEET ISL32173E, ISL32175E, ISL32177E, ISL32273E, ISL32275E, FN7529 Rev 4.00 ISL32277E April 25, 2016 These Intersil devices are 16.5kV IEC61000-4-2 ESD Features protected, 3.0V to 5.5V powered, quad receivers for balanced IEC61000 ESD protection (RS-485 inputs) 16.5kV communication using the RS-485 and RS-422 standards. Each receiver has low input currents (200A), so it presents a 1/4 - Class 3 ESD on all other pins >8kV HBM unit load to the RS-485 bus and allows up to 128 receivers on Wide supply range . 3.0V to 5.5V the bus. Wide common-mode range . -7V to +12V The ISL32173E, ISL32175E, ISL32177E are high data rate Low part-to-part propagation delay tolerance (ISL3217XE) receivers that operate at data rates up to 80Mbps. Their 8ns . 8ns (max) maximum propagation delay skew (tolerance) guarantees excellent part-to-part matching. The ISL32273E, ISL32275E, Specified for +125C operation ISL32277E are reduced supply current versions that operate at Fail-safe open Rx inputs data rates up to 20Mbps. 1/4 unit load allows 128 devices on the bus Receiver outputs are tri-statable and incorporate a hot plug Available in industry standard pinouts (ISL32173E/ feature to keep them disabled during power-up and ISL32175E ) and a 4x4 QFN (ISL32X77E) with added power-down. Versions are available with a common EN/EN features (ISL32173E pinout), a two channel EN12/EN34 (ISL32175E pinout), or a vers atile individual channel enable (see Table 1). Logic supply pin (V ) eases operation in mixed supply L systems (ISL32X77E) A 26% smaller footprint is available with the ISL32177E and High data rates up to 80Mbps or 20Mbps ISL32277E QFN packages and these two devices also feature a logic supply pin (V ). The V supply sets the switching points L L Low shutdown supply current 60A of the enable inputs and the receiver outputs V , to levels OH Tri-statable Rx outputs compatible with a lower supply voltage in mixed voltage 5V tolerant logic inputs when V = 3.3V systems. Individual channel and group enable pins increase CC the ISL32177E and ISL32277Es flexibility.
