Transmitters/Receivers
The ICL3221, ICL3222, ICL3223, ICL3232, ICL3241,
ICL3243 (ISL32xx) devices are 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 (except for the ICL3232),
reduce the standby supply current to a 1µA trickle.
Small footprint packaging, and the use of small, low
value capacitors ensure board space savings as well.
Data rates greater than 250kbps are ensured 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 that powers down the
on-chip power-supply and driver circuits. Power-down
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 on page 6 summarizes the features of the
devices represented by this datasheet, while
Application Note AN9863 summarizes the features of
each device comprising the ICL32xx 3V family.
