15kV ESD Protected, 20Mbps, 5V, Low
Power, RS-485/RS-422 Transceiver
The Intersil ISL4485E is a high speed, BiCMOS 5V
powered, single transceiver that meets both the RS-485 and
RS-422 standards for balanced communication. Each driver
output/receiver input is protected against ±15kV ESD
strikes, without latch-up. Unlike competitive devices, this
Intersil device is specified for 10% tolerance supplies (4.5V
to 5.5V).
The excellent differential output voltage coupled with high
drive-current output stages allow 20Mbps operation over
twisted pair networks up to 450 feet in length. The 25k
receiver input resistance presents a “single unit load” to the
RS-485 bus, allowing 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.
The half duplex configuration multiplexes the Rx inputs and
Tx outputs to allow transceivers with Rx and Tx disable
functions in 8 lead packages.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and 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-020.
