Data Sheet February 18, 2008
±15kV ESD Protected, 100Mbps, 5V,
PROFIBUS®, Full Fail-safe,
RS-485/RS-422 Transceivers
Intersil’s ISL3259E is a ±15kV IEC61000 ESD Protected, 5V
powered, single transceiver that meets both the RS-485 and
RS-422 standards for balanced communication. It also
features the larger output voltage and higher data rate (up to
100Mbps) required by high speed PROFIBUS applications.
The low bus currents (+220µA/-150µA) present a “1/5 unit
load” to the RS-485 bus, thus allowing 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 supply, and delivers at least a
2.1V differential output voltage. This translates into better noise
immunity (data integrity), longer reach, or the ability to drive up
to six 120Ω terminations in “star” or other non-standard bus
topologies.
SCSI applications benefit from the ISL3259’s low receiver
and transmitter part-to-part skews, which make it perfect for
high speed parallel applications where large numbers of bits
must be simultaneously captured. 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 @ V
of optically isolated interfaces.

OUT
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.

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 (floa ting) or shorted,
or connected to a terminated bus that is undriven.
RE
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.
DE 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
through a 1kΩ or greater resistor.
CC
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. This is also the potential of the DFN thermal pad.
A/Y ±15kV IEC61000 ESD Protected RS-485, RS-422 level, noninverting receiver input and noninverting driver output. Pin is an input (A)
if DE = 0; pin is an output (Y) if DE = 1.
B/Z ±15kV IEC61000 ESD Protected RS-485, RS-422 level, inverting receiver input and inverting driver output. Pin is an input (B) if
DE = 0; pin is an output (Z) if DE = 1.
