ICL3224E, ICL3226E, ICL3244E Data Sheet February 27, 2006 FN4899.6 +/-15kV ESD Protected, +3V to +5.5V, Features 1Microamp, 250kbps, RS-232 Pb-Free Plus Anneal Available (RoHS Compliant) Transceivers with Enhanced Automatic ESD Protection for RS-232 I/O Pins to 15kV (IEC61000) Powerdown 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, CC they provide 15kV ESD protection (IEC61000-4-2 Air Gap Meets EIA/TIA-232 and V.28/V .24 Specifications at 3V and Human Body Model) on transmitter outputs and receiver RS-232 Compatible with V = 2.7V CC inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the Latch-Up Free low operational, and even lower standby, power consumption On-Chip Voltage Converters Require Only Four External is critical. Efficient on-chip charge pumps, coupled with 0.1F Capacitors manual and enhanced automatic powerdown functions, reduce the standby supply current to a 1A trickle. Small Guaranteed Mouse Driveability (ICL3244E) footprint packaging, and the use of small, low value Ready to Transmit Indicator Output (ICL3224E/26E) capacitors ensure board space savings as well. Data rates Receiver Hysteresis For Improved Noise Immunity greater than 250kbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V only Guaranteed Minimum Data Rate . 250kbps systems, mixed 3.3V and 5.0V systems, and 5.0V only Guaranteed Minimum Slew Rate . 6V/ s systems. Wide Power Supply Range Single +3V to +5.5V The ICL3244E is a 3 driver, 5 receiver device that provides a complete serial port suitable for laptop or notebook Low Supply Current in Powerdown State .1 A computers. It also includes a noninverting always-active Applications receiver for wake-up capability. Any System Requiring RS-232 Communication Ports These devices, feature an enhanced automatic - Battery Powered, Hand-Held, and Portable Equipment powerdown function which powers down the on-chip power- supply and driver circuits. This occurs when all receiver and - Laptop Computers, Notebooks, Palmtops transmitter inputs detect no signal transitions for a period of - Modems, Printers and other Peripherals 30 seconds. These devices power back up, automatically, - Digital Cameras whenever they sense a transition on any transmitter or - Cellular/Mobile Phones receiver input.
