General Description
The ZT3243F Series devices are 3V powered EIA/TIA-232
and V.28/V.24 communication interfaces with low power
requirements. They consist of three line drivers, ve line re-
ceivers and the proprietary switch-capacitor regulated voltage
converters. These devices operate from a single 3V to 5.5V
power supply at the guaranteed data rate of 1000k bits/sec
with enhanced electrostatic discharge (ESD) protection in
all RS232 I/O pins exceeding ±15kV IEC1000-4-2 Air Gap
Discharge and ±8kV IEC1000-4-2 Contact Discharge.
The ZT3243F Series feature theAUTOGREEN (patent pend-
ing) proprietary function which automatically powers down the
on-chip regulated voltage converters and driver circuits when
an RS-232 cable is disconnected from the host interface or
when a connected peripheral device is turned off.

Absolute Maximum Ratings
These are stress ratings only and functional operation of the
device at these ratings or any other above those indicated
in the operation sections of the specications is not implied.
Exposure to absolute maximum rating conditions for extended
periods of time may affect reliability.

Storage Considerations
Storage in a low humidity environment is wpwrewfe.DraretadS.hLeaertg4Ue.com
high density plastic packages are moisture sensitive and
should be stored in Dry Vapor Barrier Bags. Prior to usage,
the parts should remain bagged and stored below 40°C and
60%RH. If the parts are removed from the bag, they should
be used within 48 hours or stored in an environment at or
below 20%RH. If the above conditions cannot be followed,
the parts should be baked for four hours at 125°C in order
remove moisture prior to soldering. Zywyn ships product in Dry
Vapor Barrier Bags with a humidity indicator card and desic-
cant pack. The humidity indicator should be below 30%RH.
The information furnished by Zywyn has been carefully
reviewed for accuracy and reliability. Its application or use,
however, is solely the responsibility of the user. No responsibil-
ity of the use of this information become part of the terms and
