ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E

±15kV ESD Protected, +3V to +5.5V, 1µA, 250kbps, RS-232 Transmitters/Receivers

The ICL3221E, ICL3222E, ICL3223E, ICL3232E,

ICL3241E, and ICL3243E are 3.0V to 5.5V powered

RS-232 transmitters/receivers that meet ElA/TIA-232

Features

• ESD protection for RS-232 I/O pins to ±15kV

(IEC61000)

and V.28/V.24 specifications, even at V = 3.0V.

• Drop-in replacements for the MAX3221E,

MAX3222E, MAX3223E, MAX3232E, MAX3241E,

MAX3243E, and SP3243E

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 notebook and laptop

computers in which the low operational power

consumption 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. 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 ICL3221E is a low-power, pin-compatible

upgrade for the 5V MAX221E

• The ICL3222E is a low-power, pin-compatible

upgrade for the 5V MAX242E and SP312E

• The ICL3232E is a low-power upgrade for the

HIN232E, ICL232, and pin-compatible competitor

devices

• RS-232 compatible with V = 2.7V

• Meets EIA/TIA-232 and V.28/V.24 specifications

at 3V

• Latch-up free

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.

• On-chip voltage converters require only four

external 0.1µF capacitors at V = 3.3V

• Manual and automatic power-down features

• Ensured mouse driveability (ICL324xE only)

• Receiver hysteresis for improved noise immunity

• Ensured minimum data rate: 250kbps

The ICL3221E, ICL3223E, and ICL3243E feature an

automatic power-down 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, which conserves

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.

• Wide power supply range: single +3V to +5.5V

• Low supply current in power-down state: 1µA

• Pb-free (RoHS compliant)

Applications

• Any system requiring RS-232 communication ports

Table 1 on page 2 summarizes the features of the

devices represented by this datasheet, and

Application Note AN9863 summarizes the features of

each device in the ICL32xxE 3V family.
