Datasheet
ICL3224E, ICL3226E, ICL3244E
±15kV ESD Protected, +3V to +5.5V, 1µA, 250kbps, RS-232 Transceivers with Enhanced Automatic Powerdown
The ICL3224E, ICL3226E, and ICL3244E devices are 3.0V to 5.5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. They provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational power and even lower standby power consumption are critical. Efficient on-chip charge pumps coupled with manual and enhanced automatic powerdown functions, reduce the standby supply current to a 1µA trickle.
