ICL3225EIAZ

Product Summary

The ICL3225EIAZ is a 3.0V to 5.5V powered RS-232 transmitter/receiver which meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, the ICL3225EIAZ provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications of the ICL3225EIAZ 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 enhanced automatic powerdown functions, 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 1Mbps are guaranteed at worst case load conditions. The ICL3225EIAZ is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The ICL3225EIAZ is suitable for 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.
