General Description
The ZT232E series devices are +5V powered EIA/TIA-232 and
CCITT V.28/V.24 communication interfaces with low power re-
quirements. These transceivers consist of two line drivers, two
line receivers and the proprietary switch-capacitor regulated
voltage converters. The ZT310E and ZT312E feature a low power
shutdown mode which draws as little current as 1μA typical with
receiver outputs tri-stated and in wake-up. These devices operate from
a single +5V power supply at the guaranteed data rate of 250k
bits/sec with enhanced electrostatic discharge (ESD) protection
in all RS232 I/O pins exceeding ±15kV HBM.

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 specifications 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 preferred. Large
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 168 hours or stored in an environment at or
below 20%RH. If the above conditions cannot be followed,
the parts should be baked for 12 hours at 125°C in order to
remove moisture prior to soldering. Zywyn ships product in
Dry Vapor Barrier Bags with a humidity indicator card and
desiccant pack. The humidity indicator should be below
30%RH. The MSL of this product is 3.
