DATASHEET
ISL3160E
±10kV ESD Protected, +125°C, 40Mbps, 5V, Full-Duplex, Full Fail-Safe
RS-485/RS-422 Transceiver
The
ISL3160E
is a ±10kV IEC61000 ESD protected, 5V
powered, full-duplex transceiver that meets both the
RS-485 and RS-422 standards for balanced
communication. It also features a large differential output
voltage and high data rate (up to 40Mbps) and is offered
in the standard industrial (-40°C to +85°C) and extended
industrial (-40°C to +125°C) temperature ranges. The
low bus currents (+220µA/-150µA) present a 1/5 unit
load to the RS-485 bus. This allows up to 160
transceivers on the network without violating the RS-485
specification’s load limit and without using repeaters.
This transceiver requires a 5V ±10% tolerance supply,
and delivers at least a 2.1V differential output voltage
over this supply range. This translates into better noise
immunity (data integrity), longer reach, or the ability to
drive up to six 120Ω terminations in “star” or other
nonstandard bus topologies at the exceptional 40Mbps
data rate.
SCSI applications benefit from the ISL3160E’s low
receiver and transmitter part-to-part skews. The
ISL3160E is perfect for high speed parallel applications
requiring simultaneous capture of large numbers of bits.
The low bit-to-bit skew eases the timing constraints on
the data latching signal.
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. Rx outputs
feature high drive levels (typically >30mA at V
OL
= 1V)
to ease the design of optically isolated interfaces.
Hot plug circuitry ensures that the Tx and Rx outputs
remain in a high impedance state while the power supply
stabilizes.
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.

for details about reel specifications.
2. Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Pb-free
products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J
STD-020.

Function
Receiver output.
If A - B ≥ -50mV, RO is high.
If A - B ≤ -200mV, RO is low.
If A and B are unconnected (floating) or shorted, or connected to a terminated bus that is undriven, RO is
high.
Receiver output enable.
RO is enabled when RE is low.
RO is high impedance when RE is high.
If the Rx enable function isn’t required, connect RE directly to GND.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high
impedance when DE is low. If the Tx enable function isn’t required, connect DE to V
CC
through a 1kΩ or
greater resistor.
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.
