HG3085E
General Description
Features
The HG3085E +5V, half-duplex, ±
15kV ESD-
protected
RS-485/RS-422-compatible
transceivers feature one driver and one receiver.
The HG3085E include a hot-swap capability to
eliminate false transitions on the bus during
power-up or live insertion.
TheHG3085E features reduced slew-rate drivers
that minimize EMI and reduce reflections caused
by improperly terminated cables, allowing error-
free transmission up to 500kbps.
The HG3085E feature a 1/8-unit load receiver
input impedance, allowing up to 256 transceivers
on the bus. These devices are intended for half-
duplex communications. All driver outputs are
protected to ±
15kV ESD using the Human Body
Model.
TheHG3085 is available in an 8-pin SO package.
The devices operate over the extended -40° to
C
+85° temperature range.

Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent damage
to the device. These are stress ratings only, and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of the specifications is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
