General Description
The ZT3243E 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, five 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 250k bits/sec
with enhanced electrostatic discharge (ESD) protection in
all RS232 I/O pins exceeding ±15kV IEC61000-4-2 Air Gap
Discharge and ±8kV IEC61000-4-2 Contact Discharge.
The ZT3243E 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.
