Product Summary

The ICL3243ECAZ is a 3.0V to 5.5V powered RS-232 transmitter/receiver which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, the ICL3243ECAZ provides ±15kV ESD protection on transmitter outputs and receiver inputs. Targeted applications of the ICL3243ECAZ are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical.. The ICL3243ECAZ is fully compatible with 3.3V-only systems, mixed 3.3V and 5.0V systems, and 5.0V-only systems.
