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
| Symbol | Parameter | Value | Unit |
| VCC | Supply voltage | -0.3 to 6 | V |
| V+ | Doubled voltage terminal | (VCC - 0.3) to 7 | V |
| V- | Inverted voltage terminal | 0.3 to -7 | V |
| V+ +|V- | 13 | V | |
| TIN | Transmitter input voltage range | -0.3 to 6 | V |
| RIN | Receiver input voltage range | ± 25 | V |
| TOUT | Transmitter output voltage range | ± 13.2 | V |
| ROUT | Receiver output voltage range | 0.3 to (VCC + 0.3) | V |
| tSHORT | Transmitter output short to gnd time | Continuous |
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-.
