ICL3224E, ICL3226E, ICL3244E

±15kV ESD Protected, +3V to +5.5V, 1µA, 250kbps, RS-232 Transceivers with

Enhanced Automatic Powerdown

The ICL3224E, ICL3226E, and ICL3244E devices are

3.0V to 5.5V powered RS-232 transmitters/receivers

that meet ElA/TIA-232 and V.28/V.24 specifications,

Features

• Pb-Free Plus Anneal Available (RoHS Compliant)

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

(IEC61000)

even at V = 3.0V. 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 power and even lower standby

power consumption are critical. Efficient on-chip

charge pumps coupled with manual and enhanced

automatic powerdown functions, 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.

• Manual and enhanced automatic powerdown

• Drop in replacements for MAX3224E, MAX3226E,

MAX3244E

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

• RS-232 compatible with V = 2.7V

• Latch-up free

• On-chip voltage converters require only four

external 0.1µF capacitors

• Ensured mouse driveability (ICL3244E)

• “Ready to Transmit” indicator output

(ICL3224E/ICL3226E)

The ICL3244E is a 3-driver, 5-receiver device that

provides a complete serial port suitable for laptop or

notebook computers. It also includes a noninverting

always-active receiver for “wake-up” capability.

• Receiver hysteresis for improved noise immunity

• Ensured minimum data rate 250kbps

• Ensured minimum slew rate 6V/µs

The ICL3224E, ICL3226E, and ICL3244E feature an

enhanced automatic powerdown function that powers

down the on-chip power supply and driver circuits.

Powerdown occurs when all receiver and transmitter

inputs detect no signal transitions for a period of 30s.

These devices power back up automatically

whenever they sense a transition on any transmitter

or receiver input.

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

• Low supply current in powerdown state 1µA

Applications

• Any system requiring RS-232 communication ports

○ Battery powered, hand-held, and portable

equipment

Table 1 summarizes the features of the device

represented by this datasheet and AN9863

summarizes the features of each device comprising

the ICL32xxE 3V family.

○ Laptop computers, notebooks, palmtops

○ Modems, printers, and other peripherals

○ Digital cameras

○ Cellular/mobile phones
