ICL3232CVZ

The ICL3232CVZ is a 1µA supply-current +3 to +5.5V 250kBps RS-232 Transmitter/Receiver which meet EIA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Targeted applications are PDAs, palmtops and notebook and laptop computers where the low operational and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with manual and automatic power down functions (except for the ICL3232), reduce the standby supply current to a 1µA trickle. Data rates greater than 250kBps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V only systems, mixed 3.3 and 5.0V systems and 5.0V only systems.
