General Description
The ZT32xxE series devices are 3V powered EIA/TIA-232
and V.28/V.24 communication interfaces with low power
requirements. They consist of two line drivers, two line
receivers and the proprietary switch-capacitor regulated
voltage converters. The ZT3220E has a 1Tx and 1Rx configu-
ration. These devices operate from a single 3V to 5.5V
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 EN61000-4-2 Air Gap
Discharge and ±8kV EN61000-4-2 Contact Discharge.
The ZT3221E and ZT3223E features the AUTOGREEN
(patent pending) 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.
