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. 2 3 APPLICATIONS s s s RS-232C Communication Links Modems, peripherals, computers Battery-powered systems PIN CONFIGURATIONS (DIP AND SOIC) + C1 1 + 2 – C1 3 + C2 4 – C2 5 V– 6 16 VCC 15 GND 14 T1OUT 13 R1 IN + C1 1 + 2 – C1 3 + C2 4 – C2 5 V– 6 16 VCC 15 GND 14 T1OUT 13 R1 IN ORDERING INFORMATION Part No. TC232COE TC232CPE TC232EOE TC232EPE TC232IJE TC232MJE Package 16-Pin SOIC (Wide) 16-Pin Plastic D……
