Data Sheet  
March 1, 2006  
FN4805.21  
One Microamp Supply-Current, +3V to +5.5V,  
250kbps, RS-232 Transmitters/Receivers  
Features  
• Pb-Free Plus Anneal Available as an Option  
(RoHS Compliant) (See Ordering Info)  
The Intersil ICL32XX devices are 3.0V to 5.5V powered  
RS-232 transmitters/receivers which meet ElA/TIA-232 and  
• 15kV ESD Protected (Human Body Model)  
V.28/V.24 specifications, even at V  
= 3.0V. Targeted  
CC  
• Drop in Replacements for MAX3221, MAX3222,  
MAX3223, MAX3232, MAX3241, MAX3243, SP3243  
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 ICL3232), 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.  
• ICL3221 is Low Power, Pin Compatible Upgrade for 5V  
MAX221  
• ICL3222 is Low Power, Pin Compatible Upgrade for 5V  
MAX242, and SP312A  
• ICL3232 is Low Power Upgrade for HIN232/ICL232 and  
Pin Compatible Competitor Devices  
• RS-232 Compatible with V  
CC  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• Latch-Up Free  
= 2.7V  
The ICL324X 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.  
• On-Chip Voltage Converters Require Only Four External  
0.1µF Capacitors  
• Manual and Automatic Powerdown Features (Except  
ICL3232)  
The ICL3221, ICL3223 and ICL3243, 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.  
• Guaranteed Mouse Driveability (ICL324X Only)  
• 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  
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.  
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  
- Cellular/Mobile Phones
