    One Microamp Supply-Current, +3V to +5.5V,
    250kbps, RS-232 Transmitters/Receivers
    The Intersil ICL32XX devices are 3.0V to 5.5V powered
    RS-232 transmitters/receivers which meet ElA/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
    powerdown functions (except for the ICL3232), reduce the
    standby supply current to a 1
    A trickle. Small footprint
    packaging, and the use of small, low value capacitors ensure
    board space savings as well. Data rates greater than
    250kbps are guaranteed at worst case load conditions. This
    family is fully compatible with 3.3V only systems, mixed 3.3V
    and 5.0V systems, and 5.0V only systems.
    The ICL324X are 3-driver, 5-receiver devices that provide a
    complete serial port suitable for laptop or notebook
    computers. Both devices also include noninverting always-
    active receivers for “wake-up” capability.
    The ICL3221, ICL3223 and ICL3243, feature an
    automatic powerdown function which powers down the
    on-chip power-supply and driver circuits. This occurs when
    an attached peripheral device is shut off or the RS-232
    cable is removed, conserving system power automatically
    without changes to the hardware or operating system.
    These devices power up again when a valid RS-232
    voltage is applied to any receiver input.
    Table 1 summarizes the features of the devices represented
    by this data sheet, while Application Note AN9863
    summarizes the features of each device comprising the
    ICL32XX 3V family.
