DATASHEET ICL3224E, ICL3226E, ICL3244E FN4899 Rev.6.00 +/-15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232 Transceivers Feb 27, 2006 with Enhanced Automatic Powerdown The Intersil ICL32XXE devices are 3.0V to 5.5V powered Features RS-232 transmitters/receivers which meet ElA/TIA-232 and Pb-Free Plus Anneal Available (RoHS Compliant) V.28/V.24 specifications, even at V = 3.0V. Additionally, CC they provide 15kV ESD protection (IEC61000-4-2 Air Gap ESD Protection for RS-232 I/O Pins to 15kV (IEC61000) and Human Body Model) on transmitter outputs and receiver Manual and Enhanced Automatic Powerdown Features inputs (RS-232 pins). Targeted applications are PDAs, Drop in Replacements for MAX3224E, MAX3226E, Palmtops, and notebook and laptop computers where the MAX3244E low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V coupled with manual and enhanced automatic powerdown RS-232 Compatible with V = 2.7V CC functions, reduce the standby supply current to a 1 A trickle. Small footprint packaging, and the use of small, low value Latch-Up Free capacitors ensure board space savings as well. Data rates On-Chip Voltage Converters Require Only Four External greater than 250kbps are guaranteed at worst case load 0.1F Capacitors conditions. This family is fully compatible with 3.3V only Guaranteed Mouse Driveability (ICL3244E) systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. Ready to Transmit Indicator Output (ICL3224E/26E) The ICL3244E is a 3 driver, 5 receiver device that provides a Receiver Hysteresis For Improved Noise Immunity complete serial port suitable for laptop or notebook Guaranteed Minimum Data Rate . 250kbps computers. It also includes a noninverting always-active Guaranteed Minimum Slew Rate . 6V/s receiver for wake-up capability. Wide Power Supply Range . Single +3V to +5.5V These devices, feature an enhanced automatic powerdown function which powers down the on-chip power- Low Supply Current in Powerdown State .1A supply and driver circuits. This occurs when all receiver and transmitter inputs detect no signal transitions for a period of Applications 30 seconds. These devices power back up, automatically, Any System Requiring RS-232 Communication Ports whenever they sense a transition on any transmitter or - Battery Powered, Hand-Held, and Portable Equipment receiver input. - Laptop Computers, Notebooks, Palmtops Table 1 summarizes the features of the devices represented - Modems, Printers and other Peripherals by this data sheet, while Application Note AN9863 - Digital Cameras summarizes the features of each device comprising the - Cellular/Mobile Phones ICL32XXE 3V family.
