DUAL RS-232 TRANSMITTER/RECEIVER AND POWER SUPPLY  
FEATURES  
GENERAL DESCRIPTION  
■ Meets All RS-232 Specifications  
■ Operates From Single 5V Power Supply  
■ 2 Drivers and 2 Receivers  
The TC232 is a dual RS-232 transmitter/receiver that  
complies with EIA /TIA RS-232E guidelines and is ideal for  
all RS-232 communication links. This device operates from  
a 5V power supply and contains two charge pump voltage  
converters that produce ±10V power supplies.  
The TC232 has four level translators. Two are RS-232  
transmitters that convert TTL/CMOS input levels to 9V  
RS-232 outputs. The other two translators are RS-232  
receivers that convert RS-232 inputs to 5V TTL/CMOS  
output levels. The receivers have a nominal threshold of  
1.3V, a typical hysteresis of 0.5V, and can operate with  
inputs up to ±30V.  
■ On-Board Voltage Quadrupler  
■ Input Levels.......................................................±30V  
■ Output Swing With +5V Supply .........................±9V  
■ Low Supply Current ........................................ 5 mA  
■ Does not require external ±12V supplies  
APPLICATIONS  
■ RS-232C Communication Links  
■ Modems, peripherals, computers  
■ Battery-powered systems
