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.
