DATASHEET
ISL8487E, ISL81487L, ISL81487E
±15kV ESD Protected, 1/8 Unit Load, 5V, Low Power, High Speed or Slew Rate
Limited RS-485/RS-422 Transceivers
The
ISL8487E, ISL81487L,
and
ISL81487E
RS-485/RS-422
devices are ESD protected, fractional unit load (UL),
BiCMOS, 5V powered, single transceivers that meet both
the RS-485 and RS-422 standards for balanced
communication. Each driver output/receiver input is
protected against ±15kV ESD strikes without latch-up. Unlike
competitive devices, this device family is specified for 10%
tolerance supplies (4.5V to 5.5V).
All devices present a 1/8 unit load to the RS-485 bus, which
allows up to 256 transceivers on the network for large node
count systems (for example, process automation and remote
meter reading systems). In a remote utility meter reading
system, individual utility meter readings (in apartments, for
example) are routed to a concentrator with an RS-485
network, so the high allowed node count minimizes the
number of repeaters required to network all the meters. Data
for all meters is then read out from the concentrator from a
single access port or a wireless link.
Slew rate limited drivers on the ISL8487E and ISL81487L
reduce EMI and minimize reflections from improperly
terminated transmission lines or unterminated stubs in
multidrop and multipoint applications. Data rates up to
250kbps are achievable with these devices.
Data rates up to 5Mbps are achievable by using the
ISL81487E, which features higher slew rates.
The receiver (Rx) inputs feature a “fail-safe if open” design,
which ensures a logic high Rx output if Rx inputs are floating.
The 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 half duplex devices multiplex the Rx inputs and Tx
outputs to allow transceivers with Rx and Tx disable
functions in 8 lead packages.
