Data Sheet

J uly 2004

FN4899.4

+/-15kV ESD Protected, +3V to +5.5V,

1Microamp, 250kbps , RS-232

Trans ceivers with Enhanced Automatic

Powerdown

Features

• Pb-free Available as an Option (see Ordering Information)

• ESD Protection for RS-232 I/O Pins to ±15kV (IEC61000)

• Manual and Enhanced Automatic Powerdown Features

The Intersil ICL32XXE devices are 3.0V to 5.5V powered

RS-232 transmitters/receivers which meet ElA/TIA-232 and

• Drop in Replacements for MAX3224E, MAX3226E,

MAX3244E

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

= 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 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 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.

• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V

• RS-232 Compatible with V

• Latch-Up Free

= 2.7V

• On-Chip Voltage Converters Require Only Four External

0.1µF Capacitors

• Guaranteed Mouse Driveability (ICL3244E)

• “Ready to Transmit” Indicator Output (ICL3224E/26E)

• Receiver Hysteresis For Improved Noise Immunity

• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps

• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/µs

• Wide Power Supply Range . . . . . . . Single +3V to +5.5V

• Low Supply Current in Powerdown State. . . . . . . . . . .1µA

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.

Applications

• Any System Requiring RS-232 Communication Ports

- Battery Powered, Hand-Held, and Portable Equipment

- Laptop Computers, Notebooks, Palmtops

- Modems, Printers and other Peripherals

- Digital Cameras

These devices, feature an enhanced automatic

powerdown function which powers down the on-chip power-

supply and driver circuits. This occurs when all receiver and

transmitter inputs detect no signal transitions for a period of

30 seconds. These devices power back up, automatically,

whenever they sense a transition on any transmitter or

receiver input.

- Cellular/Mobile Phones
