The KY32xx series devices are EIA/TIA-232 and V.28/V.24 communication interfaces achieve 1μA supply current with KEYSEMI’s revolutionary POWERSAVE™ feature. A proprietary, high- efficiency, dual charge-pumpregulated 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.
