±15kV ESD, 5V, Full Fail-Safe, 1/8 Unit
Load, RS-485/RS-422 Transceivers
The ISL8308xE are BiCMOS, ESD protected, 5V powered,
single transceivers that meet both the RS-485 and RS-422
standards for balanced communication. Each driver output,
and receiver input, is protected against ±15kV ESD strikes
without latch-up, and unlike competitive products, this Intersil
family is specified for 10% tolerance supplies (4.5V to 5.5V).
These devices have very low bus currents (+125µA/-75µA),
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. Data for all
meters is then read out from the concentrator via a single
access port, or a wireless link.
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.
The ISL83080E, ISL83082E, ISL83083E, ISL83084E,
ISL83085E 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.
Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state until the power supply has
stabilized, and the Tx outputs are fully short circuit protected.
The ISL83080E, ISL83083E, ISL83084E, ISL83086E 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.
