ESD Protected to ±15kV, 5V, Low Power,
High Speed or Slew Rate Limited,
RS-485/RS-422 Transceivers
These Intersil RS-485/RS-422 devices are ESD protected,
BiCMOS 5V powered, single transceivers that meet 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 family is specified for 10% tolerance supplies
(4.5V to 5.5V).
The ISL8483E utilizes slew rate limited drivers which reduce
EMI, and minimize reflections from improperly terminated
transmission lines, or unterminated stubs in multidrop and
multipoint applications.
Data rates up to 5Mbps are achievable by using the
ISL8485E which features higher slew rates.
Both devices present a “single 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.
These half duplex configurations multiplex the Rx inputs and
Tx outputs to allow transceivers with Rx and Tx disable
functions in 8 lead packages.

The ISL8483E is put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See “ ...
