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.

= 1V) to ease the design

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

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.

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.

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.

System power supply input (4.75V to 5.25V).

NC No Connection.
