UT3232 Datasheet

3.0V TO 5.5V LOW POWER MULTICHANNEL RS-232 LINE
TRANSCEIVERS USING FOR 0.1μF EXTERNAL CAPACITORS
 

 
 
DESCRIPTION
 
 
The UTC UT3232 have two receivers and two drivers, and a dual
charge-pump circuit. The device meets the requirements of
TIA/EIA-232-F and provides the electrical interface between an
asynchronous communication controller and the serial-port connector.
The charge pump and four small external capacitors allow operation
from a single 3.0V to 5.5V supply. The device operates at data
signaling rates up to 250kbit/s and a maximum of 35V/μs driver output
slew rate.
      
 
FEATURES
 
 
* Exceeds ±8KV ESD Protection(HBM) for RS-232 I/O Pins
* Meets the Requirements of TIA/EIA-232-F and ITU V.28 Standards
* Operates With 3.0V to 5.5V VCC Supply
* Operates Up To 250kbit/s Data Rate
* Two Drivers and Two Receivers
* External Capacitors 4×0.1μF
* Accepts 5.0V Logic Input With 3.3V Supply
