ISL81334, ISL41334

±15kV ESD Protected, Two Port, Dual Protocol Transceivers

FN6202

Rev.4.00

Mar 24, 2017

The ISL81334 and ISL41334 are two-port interface ICs in

Features

which each port can be independently configured as a single

RS-485, RS-422 transceiver, or as a dual (2 Tx, 2 Rx) RS-232

transceiver. With both ports set to the same mode, two

RS-485, RS-422 transceivers, or four RS-232 transceivers are

available.

• ±15kV (HBM) ESD protected bus pins (RS-232 or RS-485)

• Two independent ports, each user selectable for RS-232

(2 transceivers) or RS-485, RS-422 (1 transceiver)

• Single 5V (10% tolerance) supply

• Flow-through pinouts simplify board layouts

• Pb-Free (RoHS compliant)

If either port is in RS-232 mode, the onboard charge pump

generates RS-232 compliant ±5V Tx output levels from a

single V supply as low as 4.5V. Four small 0.1µF capacitors

are required for the charge pump. The transceivers are RS-232

compliant, with the Rx inputs handling up to ±25V, and the Tx

outputs handling ±12V.

• Large (2.7V) differential V

OUT

in RS-485, RS-422 networks

for improved noise immunity

• Full fail-safe (open/short) Rx in RS-485, RS-422 mode

• Loopback mode facilitates board self-test functions

In RS-485 mode, the transceivers support both the RS-485

and RS-422 differential communication standards. The

receivers feature “full fail-safe” operation, so the Rx outputs

remain in a high state if the inputs are open or shorted

together. The transmitters support up to three data rates, two

of which are slew rate limited for problem-free

• User selectable RS-485 data rates (ISL41334 only)

communications. The charge pump disables when both ports

are in RS-485 mode, thereby saving power, minimizing noise,

and eliminating the charge pump capacitors.

• QFN package saves board space (ISL41334 only)

Both RS-232 and RS-485 modes feature loopback and

shutdown functions. Loopback internally connects the Tx

outputs to the corresponding Rx input, to facilitate board level

self-test implementation. The outputs remain connected to the

loads during loopback, so connection problems (such as

shorted connectors or cables) can be detected. Shutdown

mode disables the Tx and Rx outputs, disables the charge

pumps, and places the IC in a low current (µA) mode.

• Logic supply pin (V ) eases operation in mixed supply

systems (ISL41334 only)

Applications

• Gaming applications (such as, slot machines)

• Single board computers

• Factory automation

The ISL41334 is a QFN packaged device that includes two

additional user selectable, lower speed, and edge rate options

for EMI-sensitive designs, or to allow longer bus lengths. It also

• Security networks

• Industrial/process control networks

• Level translators, such as RS-232 to RS-422

• Point of sale equipment

features a logic supply pin (V ) that sets the V level of logic

outputs, and the switching points of logic inputs, to be

compatible with another supply voltage in mixed voltage

systems. The QFN also adds active low Rx enable pins to

increase design flexibility, allowing Tx/Rx direction control,

through a single signal per port, by connecting the

corresponding DE and RXEN pins together.

• Dual channel RS-485 interfaces
