Renesas Electronics ICL3232CBNZ-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.
