UT232A
Preliminary

APPLICATION INFORMATION
To operate from a single +5V supply, the UTC UT232A include charge pump voltage converters which can allow
it. 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.
UTC assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specifications of any and all UTC products described or contained
herein. UTC products are not designed for use in life support appliances, devices or systems where
malfunction of these products can be reasonably expected to result in personal injury. Reproduction in
