5V, Ultra High Speed, PROFIBUS®,
RS-485/RS-422 Transceivers
The Intersil ISL4486 and ISL81486 are BiCMOS, 5V
powered, single transceivers that meet both the RS-485 and
RS-422 standards for balanced communication, and feature
the larger output voltage and higher data rate - up to
40Mbps - required by high speed PROFIBUS applications.
Unlike competitive products, these Intersil devices are
specified for 10% tolerance supplies (4.5V to 5.5V) and
deliver at least a 2.3V differential output voltage over this
supply range. At the 5% tolerance specified by many
competitors, the ISL4486 delivers an unsurpassed 2.5V
differential signal into a 54Ω total load. This translates into
longer reach, or better data integrity, at the exceptional
40Mbps data rate.
SCSI applications benefit from the ISL4486’s low receiver
and transmitter part-to-part skews, which make it perfect for
high speed parallel applications where large numbers of bits
must be simultaneously captured. The low bit-to-bit skew
eases the timing constraints on the data latching signal.
These devices present a “0.6 unit load” to the RS-485 bus,
which allows up to 50 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.
