5V, Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
The Intersil RS-485/RS-422 devices are BiCMOS 5V
powered, single transceivers that meet both the RS-485 and
RS-422 standards for balanced communication. Unlike
competitive devices, this Intersil family is specified for 10%
tolerance supplies (4.5V to 5.5V).
The ISL8483, ISL8488, and ISL8489 utilize 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
ISL8485, ISL8490, or ISL8491, which feature higher slew
rates.
All 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.
The ISL8488 - 91 are configured for full duplex (separate Rx
input and Tx output pins) applications. The ISL8488 and
ISL8490 are offered in space saving 8 lead packages for
applications not requiring Rx and Tx output disable functions
(e.g., point-to-point). Half duplex configurations (ISL8483,
ISL8485) multiplex the Rx inputs and Tx outputs to allow
transceivers with Rx and Tx disable functions in 8 lead
packages.
