ICL3221IAZ-T

ICL3221IAZ-T is a one microamp supply current, +3V to +5.5V, 250kbps, RS-232 transmitters/receiver that meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Targeted applications are PDAs, notebooks, 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. Applications include any system requiring RS-232 communication ports, battery powered, hand-held, and portable equipment, laptop computers, notebooks, modems, printers, and other peripherals, digital cameras, cellular/mobile phones.
