ICL3225, ICL3245 Data Sheet October 5, 2015 FN4878.9 1 Microamp, +3V to +5.5V, 1Mbps, RS-232 Features Transceivers with Enhanced Automatic 15kV ESD Protected (Human Body Model) Powerdown Manual and Enhanced Automatic Powerdown Features The Intersil ICL32XX devices are 3.0V to 5.5V powered Drop in Replacements for MAX3225, MAX3245 RS-232 transmitters/receivers which meet ElA/TIA-232 and Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V V.28/V.24 specifications, even at V = 3.0V. Targeted CC applications are PDAs, Palmtops, and notebook and laptop Latch-Up Free computers where the low operational, and even lower On-Chip Voltage Converters Require Only Four External standby, power consumption is critical. Efficient on-chip 0.1F Capacitors charge pumps, coupled with manual and enhanced automatic powerdown functions, reduce the standby supply Guaranteed Mouse Driveability (ICL3245) current to a 1A trickle. Small footprint packaging, and the Ready to Transmit Indicator Output (ICL3225) use of small, low value capacitors ensure board space Receiver Hysteresis For Improved Noise Immunity savings as well. Data rates greater than 1Mbps are guaranteed at worst case load conditions. This family is fully Guaranteed Minimum Data Rate 1Mbps compatible with 3.3V only systems, mixed 3.3V and 5.0V Low Skew at Transmitter/Receiver Input Trip Points . 10ns systems, and 5.0V only systems. Guaranteed Minimum Slew Rate 24V/s The ICL3245 is a 3 driver, 5 receiver device that provides a complete serial port suitable for laptop or notebook Wide Power Supply Range . Single +3V to +5.5V computers. It also includes a noninverting always-active Low Supply Current in Powerdown State .1A receiver for wake-up capability. Pb-Free Plus Anneal Available (RoHS Compliant) These devices, feature an enhanced automatic powerdown function which powers down the on-chip power- Applications supply and driver circuits. This occurs when all receiver and Any System Requiring RS-232 Communication Ports transmitter inputs detect no signal transitions for a period of - Battery Powered, Hand-Held, and Portable Equipment 30s. These devices power back up, automatically, whenever - Laptop Computers, Notebooks, Palmtops they sense a transition on any transmitter or receiver input. - Modems, Printers and other Peripherals Table 1 summarizes the features of the device represented - Digital Cameras by this data sheet, while Application Note AN9863 - Cellular/Mobile Phones summarizes the features of each device comprising the ICL32XX 3V family.
