ISL81485
5V, 30Mbps, RS-485/RS-422 Transceiver
The Intersil ISL81485 is a BiCMOS, 5V powered, single
transceiver that meets both the RS-485 and RS-422
standards for balanced communication, and features a larger
output voltage and higher data rate to benefit high speed
applications.
Unlike competitive devices, this Intersil transceiver is
specified for 10% tolerance supplies (4.5V to 5.5V), and it
delivers a much larger worst case differential output voltage
(2.0V compared to the typical 1.5V) over the full supply
range. The increased output voltage translates into longer
reach, or better data integrity, at the 30Mbps data rate.
This device presents a “1 unit load” to the RS-485 bus, which
allows up to 32 transceivers on the network.
Receiver (Rx) inputs feature a “fail-safe if open” design,
which ensures a logic high Rx output if Rx inputs are
floating.
Driver (Tx) outputs are short circuit protected, even for
voltages exceeding the power supply voltage. Additionally,
on-chip thermal shutdown circuitry disables the Tx outputs to
prevent damage if power dissipation becomes excessive.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
