Renesas Electronics ICL3222EIVZ-T Line Transceiver

The Renesas RS-232 transmitter/receiver is 3.0V to 5.5V powered ,RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications even at VCC 3.0V. Additionally it provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are notebook and laptop computers in which the low operational power consumption and even lower standby power consumption is critical.

Latch-up free
On-chip voltage converters require only four external 0.1μF capacitors at VCC 3.3V
Manual and automatic power-down features
Receiver hysteresis for improved noise immunity
Ensured minimum data rate of 250kbps
Wide power supply range of single +3V to +5.5V
