±15kV ESD Protected, +3V to +5.5V, 1µA, 250kbps,

RS-232 Transmitters/Receivers

ICL3221E, ICL3222E, ICL3223E,

ICL3232E, ICL3241E, ICL3243E

The Intersil ICL32xxE 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 V

Additionally, they provide

(IEC61000-4-2 Air Gap and Human Body Model) on

transmitter outputs and receiver inputs (RS-232 pins).

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

ICL3232E), 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 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 ICL324XE 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 ICL3221E, ICL3223E and ICL3243E, feature an

automatic power-down 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.
