Renesas Electronics ICL3243ECAZ-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, coupled with manual and automatic power-down functions, reduce the standby supply current to a 1μA trickle.

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
Low supply current in power-down state of 1μA
Pb-free (RoHS compliant)
