UT3232
Preliminary
CMOS IC
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 dua l
charge-pump circuit. T he devic e meets the req uirements o f
TIA/EIA-232-F and p rovides the el ectrical i nterface be tween a n
asynchronous communication controller and the serial-port connector.
The charge p ump and fo ur small external capacitors allow operation
from a single 3. 0V to 5. 5V su pply. T he device operates at data
signaling rates up to 250kbit/s and a maximum of 35V/μs driver output
slew rate.

Notes: 1. All typical values are at VCC=3.3V or VCC=5.0V, and TA=25°C.
2. Short-circuit durations should be controlled to prevent exceeding the device absolute power-dissipation
ratings, and not more than one output should be shorted at a time.
3. Test conditions are C1~C4=0.1μF at VCC=3.3V±0.3V; C1=0.047μF, C2~C4=0.33μF at VCC=5.0V±0.5V.
4. Pulse skew is defined as |tPLH−tPHL| of each channel of the same device.
