Data Sheet

FN4910.18

±15kV ESD Protected, +3V to +5.5V,

1Microamp, 250kbps, RS-232

Transmitters/Receivers

Features

• Pb-free Available (RoHS Compliant) (See Ordering Info)

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

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 MAX3221E, MAX3222E,

MAX3223E, MAX3232E, MAX3241E, MAX3243E,

SP3243E

• ICL3221E is a Low Power, Pin Compatible Upgrade for 5V

MAX221E

• ICL3222E is a Low Power, Pin Compatible Upgrade for 5V

MAX242E, and SP312E

• ICL3232E is a Low Power Upgrade for HIN232E, ICL232

and Pin Compatible Competitor Devices

• RS-232 Compatible with V

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

• Latch-Up Free

• On-Chip Voltage Converters Require Only Four External

0.1µF Capacitors

• Manual and Automatic Powerdown Features

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 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.

= 2.7V

• Guaranteed Mouse Driveability (ICL324XE Only)

• Receiver Hysteresis For Improved Noise Immunity

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

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

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

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.

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
