Renesas Electronics ICL3232EIAZ-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.Targeted applications are PDAs, notebook, and laptop computers where the low operational power consumption and even lower standby power consumption are critical. Efficient on chip charge pumps, reduce the standby supply current to a 1μA trickle.

Latch-up free
On-chip voltage converters require only four external 0.1μF capacitors
Receiver hysteresis for improved noise immunity
Assured minimum data rate of 250kbps
Assured minimum slew rate of 6V/μs
Wide power supply range of single +3V to +5.5V
Low supply current in power down state of 1μA
Pb-free (RoHS compliant)
