The Renesas RS-232 Transmitters/Receiver is 2.7V to 5.5V powered that meet ElA/TIA-232 and V.28/V.24 specifications even at VCC 3.0V. They provide ±15kV ESD protection (IEC61000-4-2 air gap and human body model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and hand-held products where the low operational power consumption and even lower standby power consumption are critical. Efficient on-chip charge pumps coupled with manual and automatic power down functions, reduce the standby supply current to a 150nA trickle.

RS-232 compatible with VCC 2.7V

On-chip voltage converters require only four external 0.1μF capacitors

Receiver hysteresis for improved noise immunity

Assured minimum data rate of 250kbps

Wide power supply range of single +2.7V to +5.5V

Pb-free (RoHS compliant)
