+3V to +5.5V RS-232 Transceivers 

Request full datasheet:  Click here 
The GI32xx series devices are EIA/TIA-232 and V.28/V.24 communication interfaces achieve 1µA supply current with GIC’s revolutionary POWERSAVE™ feature. A proprietary, high-efficiency, dual charge-pump regulated voltage converters and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply.
These devices can operate from input voltages ranging from +3.0V to +5.5V 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 POWERSAVE 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. The system turns on again when a valid level is applied to any RS-232 receiver input.
