1 / 6 page 1 TM June 2001 ICL232 +5V Powered, Dual RS-232 Transmitter/Receiver File Number 3020.6 Features • Meets All RS-232C and V.28 Specifications • Requires Only Single +5V Power Supply • Onboard Voltage Doubler/Inverter • Low Power Consumption •2 Drivers - ±9V Output Swing for +5V lnput -300 Ω Power-off Source Impedance - Output Current Limiting - TTL/CMOS Compatible -30V/ µs Maximum Slew Rate • 2 Receivers - ±30V Input Voltage Range -3k Ω to 7kΩ Input Impedance - 0.5V Hysteresis to Improve Noise Rejection • All Critical Parameters are Guaranteed Over the Entire Commercial, Industrial and Military Temperature Ranges Applications • Any System Requiring RS-232 Communications Port - Computer - Portable and Mainframe - Peripheral - Printers and Terminals - Portable Instrumentation - Modems • Dataloggers Description 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. The drivers feature true TTL/CMOS input compatibility, slew- rate-limited output, and 300 Ω power-off source impedance. The receivers can handle up to +30V, and have a 3k Ω to 7kΩ input impedance. The receivers also have hysteresis to improve noise rejection. Ordering Information PART NUMBER TEMP. RANGE (oC) PACKAGE PKG. NO.
