±16.5kV ESD (IEC61000-4-2) Protected,
Large Output Swing, 5V, Full Fail-Safe, 1/8
Unit Load, RS-485/RS-422 Transceivers
The ISL315XE are BiCMOS, IEC61000 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 ±16.5kV ESD
strikes without latch-up.
The ISL315XE transmitters all deliver exceptional differential
output voltages (2.4V min), into the RS-485 required 54Ω
load, for better noise immunity or to allow up to eight 120Ω
terminations in “star” or other non-standard bus topologies.
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.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or on a terminated but undriven bus. Rx outputs
feature high drive levels - typically 28mA @ VOL = 1V (to ease
thewww.DataSheet4U.com design of optocoupled isolated interfaces).
The ISL3150E, ISL3152E, ISL3153E, ISL3155E utilize slew
rate limited drivers which reduce EMI, and minimize reflections
from improperly terminated transmission lines, or unterminated
stubs in multidrop and multipoint applications.
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 ISL3150E, ISL3153E, ISL3156E are configured for full
duplex applications. The half duplex versions multiplex the
Rx inputs and Tx outputs to allow transceivers with output
disable functions in 8 Ld packages.

Pin Descriptions
PIN FUNCTION
RO Receiver output: If A-B -50mV, RO is high; If A-B -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.
RE Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high.
DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low.
DI Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
GND Ground connection.
A/Y ±16.5kV IEC61000 ESD Protected RS-485/422 level, noninverting receiver input and noninverting driver output. Pin is an input if
DE = 0; pin is an output if DE = 1.
B/Z ±16.5kV IEC61000 ESD Protected RS-485/422 level, Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin
is an output if DE = 1.
A ±16.5kV IEC61000 ESD Protected RS-485/422 level, noninverting receiver input.
B ±16.5kV IEC61000 ESD Protected RS-485/422 level, inverting receiver input.
Y ±16.5kV IEC61000 ESD Protected RS-485/422 level, noninverting driver output.
Z ±16.5kV IEC61000 ESD Protected RS-485/422 level, inverting driver output.
VCC System power supply input (4.5V to 5.5V).
