To generate the RS-232 output levels these converters convert the +5V input power to the ±10V needed. The current drain due to charge pump operation is considerably reduced, typically to 400µA with this power supplied externally. The UTC UT232A can operate over the commercial, industrial and military temperature ranges. Protection from Shorts to ±15V Against shorts to ground, any other driver output, and V+ or V- the driver outputs are protected. If the outputs is connected to voltages higher than ±15V inadvertently, then the external protection is recommended to be provided. While voltages exceeding ±15V ,for protection, two back-to-back zener diodes which is connected from each output to ground will clamp the outputs to an acceptable voltage level.
