Datasheet

ICL3221, ICL3222, ICL3223, ICL3232, ICL3241, ICL3243

One Microamp Supply-Current, +3V to +5.5V, 250kbps, RS-232

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

Features

• RoHS Compliant

• 15kV ESD protected (Human Body Model)

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

• Drop-in replacements for MAX3221, MAX3222,

MAX3223, MAX3232, MAX3241, MAX3243,

SP3243

• ICL3221 is a low-power, pin compatible upgrade for

5V MAX221

• ICL3222 is a low-power, pin compatible upgrade for

5V MAX242, and SP312A

• ICL3232 is a low-power upgrade for HIN232/ICL232

and pin compatible competitor devices

• RS-232 compatible with V = 2.7V

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

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.

• Latch-up free

• On-chip voltage converters require only four

external 0.1µF capacitors

• Manual and automatic powerdown features (except

ICL3232)

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.

• Assured mouse driveability (ICL324x only)

• Receiver hysteresis for improved noise immunity

• Assured minimum data rate: 250kbps

• Assured minimum slew rate: 6V/μs

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

• Low supply current in powerdown state:1µA

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.

Applications

• Any system requiring RS-232 communication ports

○ Battery powered, hand-held, and portable

equipment
