ISL81334, ISL41334

Data Sheet

December 1, 2005

FN6202.0

±15kV ESD Protected, Two Port, Dual

Features

Protocol Trans ceivers

• ±15kV (HBM) ESD Protected Bus Pins (RS-232 or

RS-485)

The ISLX1334 are two port interface ICs where each port

can be independently configured as a single RS-485/422

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

With both ports set to the same mode, two RS-485/422

transceivers, or four RS-232 transceivers are available.

• Two Independent Ports, Each User Selectable for RS-232

(2 Transceivers) or RS-485/422 (1 Transceiver)

• Flow-Through Pinouts Simplify Board Layouts

• Pb-Free Plus Anneal Available (RoHS Compliant)

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

• Large (2.7V) Differential V

for Improved Noise

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

OUT

Immunity in RS-485/422 Networks

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.

• Full Failsafe (Open/Short) Rx in RS-485/422 Mode

• Loopback Mode Facilitates Board Self Test Functions

• User Selectable RS-485 Data Rates (ISL41334 Only)

- Fast Speed . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20Mbps

- Slew Rate Limited. . . . . . . . . . . . . . . . . . . . . . . 460kbps

- Slew Rate Limited. . . . . . . . . . . . . . . . . . . . . . . 115kbps

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

and RS-422 differential communication standards. The

receivers feature "full failsafe" 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

communications. The charge pump disables when both

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

noise, and eliminating the charge pump capacitors.

• Fast RS-232 Data Rate . . . . . . . . . . . . . . . Up to 650kbps

• Low Current Shutdown Mode. . . . . . . . . . . . . . . . . . .42µA

• QFN Package Saves Board Space (ISL41334 Only)

• Logic Supply Pin (V ) Eases Operation in Mixed Supply

Systems (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 (e.g., 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.

Applications

• Gaming Applications (e.g., Slot Machines)

• Single Board Computers

• Factory Automation

• Security Networks

• Industrial/Process Control Networks

• Level Translators (e.g., RS-232 to RS-422)

• Point of Sale Equipment

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 features a logic supply pin (V ) that sets the

• Dual Channel RS-485 Interfaces

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, via a single signal per port, by connecting

the corresponding DE and RE pins together.

For a single port version of these devices, please see the
