±15kV ESD Protected, +3V to +5.5V,

1Microamp, 250kbps, RS-232

Transmitters/Receivers

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

they provide

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 powerdown 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 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

ICL32xxE 3V family.
