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 VCC

= 3.0V. Additionally, they provide ±15kV ESD

protection (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.

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 ICL32xxE 3V family.
