ICL3224, ICL3226, ICL3238, ICL3244 Data Sheet March 1, 2006 FN4876.10 1 Microamp, +3V to +5.5V, 250kbps, Features RS-232 Transceivers with Enhanced Pb-Free Plus Anneal Available (RoHS Compliant) Automatic Powerdown 15kV ESD Protected (Human Body Model) The Intersil ICL32XX devices are 3.0V to 5.5V powered Manual and Enhanced Automatic Powerdown Features RS-232 transmitters/receivers which meet ElA/TIA-232 and Drop in Replacements for MAX3224, MAX3226, V.28/V.24 specifications, even at V = 3.0V. Targeted CC MAX3238, MAX3244 applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V standby, power consumption is critical. Efficient on-chip Latch-Up Free charge pumps, coupled with manual and enhanced RS-232 Compatible with V = 2.7V automatic powerdown functions, reduce the standby supply CC current to a 1A trickle. Small footprint packaging, and the On-Chip Voltage Converters Require Only Four External use of small, low value capacitors ensure board space 0.1F Capacitors savings as well. Data rates greater than 250kbps are Flow-Through Pinout (ICL3238) guaranteed at worst case load conditions. This family is fully Guaranteed Mouse Driveability (ICL3244) compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. Ready to Transmit Indicator Output (ICL3224/26) The ICL3244 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. The ICL3244/38 also include a noninverting Guaranteed Minimum Slew Rate . 6V/s always-active receiver for RING INDICATOR monitoring. 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 30sec. 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 ICL32XX 3V family. - Data Cradles Related Literature Technical Brief TB363 Guidelines for Handling and Processing Moisture Sensitive Surface Mount Devices (SMDs) AN9863, 3V to +5.5V, 250k-1Mbps, RS-232 Transmitters/Receivers TABLE 1.
