Low Power +3V to +5.5V, 250kbps RS232 Transceivers

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.
