Description
The ST3232 is a 3 V powered EIA/TIA-232 and V.28/V.24
communication interface with low power requirements, high
data-rate capabilities. ST3232 has a proprietary low dropout
transmitter output stage providing true RS-232 performance
from 3 to 5.5 V supplies. The device requires only four small
0.1 mF standard external capacitors for operations from 3 V
supply. The ST3232 has two receivers and two drivers. The
device is guaranteed to run at data rates of 250 kbps while
maintaining RS-232 output levels. Typical applications are Not
-ebook, Subnotebook and Palmtop Computers, Battery Powered

Absolute maximum ratings

Note: Absolute maximum ratings are those values beyond which damage to the device may occur.
Functional operation under these condition is not implied.
Externally applied V+ and V- can have a maximum magnitude of +7 V, but their absolute
addition can not exceed 13 V.

Running on internal charge pump, intrinsic self limitation allows exceeding those values
without any damage.
Startup voltage sequence (VCC, then V+, then V-) is critical, therefore it is not recommended
to use this device using externally applied voltage to V+ and V-.
