Data Sheet
±
15kV ESD Protected, 3.3V, Full Fail-safe,
Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
The Intersil ISL8307XE are BiCMOS 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 ISL83070E through ISL83075E 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 ISL83070E, ISL83071E, ISL83073E, ISL83076E,
ISL83077E 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 lead packages.
