Rev 4.00
July 27, 2015 Features The Intersil ISL3280E, ISL3281E, ISL3282E, ISL3283E,
ISL3284E, ISL3285E are В±16.5kV IEC61000 ESD Protected,
3.0V to 5.5V powered, single receivers that meet both the
RS-485 and RS-422 standards for balanced communication.
These receivers have very low bus currents (+125ВµA/-100ВµA),
so they present a true “1/8 unit load” to the RS-485 bus. This
allows up to 256 receivers on the network without violating the
RS-485 specification’s 32 unit load maximum and without using
repeaters. IEC61000 ESD protection on RS-485 inputs . В±16.5kV
-Class 3 ESD level on all other pins . .>5kV HBM Pb-free (RoHS compliant) Wide supply range . 3.0V to 5.5V Specified for +125В°C operation Logic supply pin (VL) eases operation in mixed supply
systems (ISL3282E, ISL3284E, ISL3285E only) Receiver inputs feature a “Full Fail-Safe” design, which ensures
a logic high Rx output if Rx inputs are floating, shorted, or
terminated but undriven. Full fail-safe (open, short, terminated/undriven) True 1/8 unit load allows up to 256 devices on the bus The ISL3280E and ISL3284E feature an always enabled Rx;
the ISL3281E and ISL3285E feature an active high Rx enable
pin and the ISL3282E and ISL3283E include an active low
enable pin. All versions are offered in Industrial and Extended
Industrial (-40В°C to +125В°C) temperature ranges. High data rates up to 20Mbps Low quiescent supply current . 500ВµA (max)
-Very low shutdown supply current 20ВµA (max) -7V to +12V common mode input voltage range A 26% smaller footprint is available with the ISL3282E and
ISL3285E TDFN package. These devices, plus the ISL3284E, …
