±15kV ESD Protected, 3.3V, Full Fail-Safe,
Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
The Intersil ISL317XE are
3.3V-powered, single transceivers that meet both the
RS-485 and RS-422 standards for balanced communication.
These devices have very low bus currents (+125mA/-100mA),
so they present a true “1/8 unit load” to the RS-485 bus. This
allows up to 256 transceivers on the network without violating
the RS-485 specification’s 32 unit load maximum, and without
using repeaters. For example, in a remote utility meter reading
system, individual meter readings are routed to a concentrator
via an RS-485 network, so the high allowed node count
minimizes the number of repeaters required.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or terminated but undriven.
Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state while the power supply stabilizes.
The ISL3170E through ISL3175E utilize slew rate limited
drivers which reduce EMI, and minimize reflections from
improperly terminated transmission lines, or unterminated
stubs in multidrop and multipoint applications. Slew rate limited
versions also include receiver input filtering to enhance noise
immunity in the presence of slow input signals.
The ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E,
ISL3177E are configured for full duplex (separate Rx input
and Tx output pins) applications. The half duplex versions
multiplex the Rx inputs and Tx outputs to allow transceivers
with output disable functions in 8 Ld packages.
