s s s s s s s s Meets All RS-232 Specifications Operates From Single 5V Power Supply 2 Drivers and 2 Receivers On-Board Voltage Quadrupler Input Levels ...................................................... ±30V Output Swing With +5V Supply ........................ ±9V Low Supply Current ........................................ 5 mA Does not require external ±12V supplies GENERAL DESCRIPTION
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. 2 3 4 APPLICATIONS
