5 / 6 page ![]() UT232A CMOS IC UNISONICTECHNOLOGIESCO.,LTD 5 of 6 www.unisonic.com.tw QW-R502-272.F APPLICATION INFORMATION To operate from a single +5.0V supply, the UTC UT232A include charge pump voltage converters which can allow it. To generate the RS-232 output levels these converters convert the +5.0V input power to the ±9V needed. The current drain due to charge pump operation is considerably reduced with this power supplied externally. The UTC UT232A can operate over the commercial, industrial and military temperature ranges. Connecting the capacitor to VCC (+5.0V) is recommended. 1 3 0.1µF + 4 5 0.1µF + Voltage Doubler VCC 16 Voltage Inverter T1 14 T1OUT T1IN 11 400kΩ T2 7 T2OUT T2IN 10 12 9 R1OUT R2OUT TTL/CMOS INPUTS TTL/CMOS OUTPUTS 5kΩ 0.1µF 0.1µF + 2 6 R1IN R2IN RS-232 INPUTS RS-232 OUTPUTS +5V INPUT V+ V- 13 8 R2 R1 GND + C1+ C1- C2+ C2- 15 400kΩ 5kΩ |
