ICL232  
+5V Powered, Dual RS-232 Transmitter/Receiver  
August 1997  
Features  
Description  
• Meets All RS-232C and V.28 Specifications  
• Requires Only Single +5V Power Supply  
• Onboard Voltage Doubler/Inverter  
• Low Power Consumption  
The ICL232 is a dual RS-232 transmitter/receiver interface  
circuit that meets all ElA RS-232C and V.28 specifications. It  
requires a single +5V power supply, and features two  
onboard charge pump voltage converters which generate  
+10V and -10V supplies from the 5V supply.  
• 2 Drivers  
The drivers feature true TTL/CMOS input compatibility, slew-  
rate-limited output, and 300power-off source impedance.  
The receivers can handle up to +30V, and have a 3kto 7kΩ  
input impedance. The receivers also have hysteresis to  
improve noise rejection.  
- ±9V Output Swing for +5V lnput  
- 300Power-off Source Impedance  
- Output Current Limiting  
- TTL/CMOS Compatible  
- 30V/µs Maximum Slew Rate
