Data Sheet

March 1, 2006

FN4876.10

1 Microamp, +3V to +5.5V, 250kbps ,

RS-232 Trans ceivers with Enhanced

Automatic Powerdown

Features

• Pb-Free Plus Anneal Available (RoHS Compliant)

• ±15kV ESD Protected (Human Body Model)

The Intersil ICL32XX devices are 3.0V to 5.5V powered

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

• Manual and Enhanced Automatic Powerdown Features

• Drop in Replacements for MAX3224, MAX3226,

MAX3238, MAX3244

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

= 3.0V. 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

• Latch-Up Free

• RS-232 Compatible with V

= 2.7V

• On-Chip Voltage Converters Require Only Four External

0.1µF Capacitors

• Flow-Through Pinout (ICL3238)

• Guaranteed Mouse Driveability (ICL3244)

• “Ready to Transmit” Indicator Output (ICL3224/26)

• 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 ICL3244 is a 3 driver, 5 receiver device that provides a

complete serial port suitable for laptop or notebook

computers. The ICL3244/38 also include a noninverting

always-active receiver for RING INDICATOR monitoring.

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

30sec. These devices power back up, automatically,

whenever they sense a transition on any transmitter or

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

Table 1 summarizes the features of the devices represented

by this data sheet, while Application Note AN9863

summarizes the features of each device comprising the

ICL32XX 3V family.

- Cellular/Mobile Phones

- Data Cradles
