±16.5kV ESD, Large Output Swing, 5V, Full Fail-Safe, 1/8 Unit Load,
RS-485/RS-422 Transceivers
The ISL315xE are IEC61000 ESD protected, 5V
powered transceivers that meet the RS-485 and
RS-422 standards for balanced communication. Driver
outputs and receiver inputs are protected against
±16.5kV ESD strikes without latch-up.
Transmitters in this family 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”
topologies.
These devices have very low bus currents so they
present a true “1/8 unit load” to the RS-485 bus. This
allows up to 256 transceivers on the network 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 at V
OL
= 1V (to ease the design of optocoupled
isolated interfaces).
Half duplex (Rx inputs and Tx outputs multiplexed
together) and full duplex pinouts are available. See
Table 1 on page 2
for key features and configurations
by device number.

FUNCTION
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.
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when
DE is low.
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.
Ground connection.
