These Intersil devices are В±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 (В±200ВµA), 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
power-down. Versions are available with a common EN/EN
(ISL32173E pinout), a two channel EN12/EN34 (ISL32175E
pinout), or a vers atile 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 …
