Data Sheet

FN6202.3  
±15kV ESD Protected, 5V, Two Port, Dual  
Features  
Protocol (RS-232/RS-485) Transceivers  
• ±15kV (HBM) ESD Protected Bus Pins (RS-232 or  
RS-485)  
The ISL81334, ISL41334 are two port interface ICs where  
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.  
• 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.  
• Full Failsafe (Open/Short) Rx in RS-485, RS-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  
L
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.  
Systems (ISL41334 Only)  
Applications  
• Gaming Applications (e.g., Slot Machines)  
• Single Board Computers  
• Factory Automation  
• Security Networks  
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  
• Industrial/Process Control Networks  
• Level Translators (e.g., RS-232 to RS-422)

lengths. It also features a logic supply pin (V ) that sets the

level of logic outputs, and the switching points of logic  
OH  
• Dual Channel RS-485 Interfaces  
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 RXEN pins together.  
For a single port version of these devices, please see the
