Low Power +3V to +5.5V, 3D/5R 1000kbps RS232 Transceivers General Description The ZT3243F Series devices are 3V powered EIA/TIA-232 and V.28/V.24 munication interfaces with low power requirements. They consist of three line drivers, five line receivers 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 ±15k V IEC1000-4-2 Air Gap Discharge and ±8k V IEC1000-4-2 Contact Discharge. The ZT3243F Series feature 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.
