Data Sheet  
November 2002  
FN4876.6  
1 Microamp, +3V to +5.5V, 250kbps,  
RS-232 Transceivers with Enhanced  
Automatic Powerdown  
Features  
• ±15kV ESD Protected (Human Body Model)  
• Manual and Enhanced Automatic Powerdown Features  
The Intersil ICL32XX devices are 3.0V to 5.5V powered  
RS-232 transmitters/receivers which meet ElA/TIA-232 and  
• Drop in Replacements for MAX3224, MAX3226,  
MAX3238, MAX3244  
V.28/V.24 specifications, even at V  
= 3.0V. Targeted  
CC  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• Latch-Up Free  
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.  
• RS-232 Compatible with V  
CC  
= 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
