±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 ±15kV IEC61000 ESD protected,
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 using 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,
and 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.
