ICL3221EFVZ - Renesas Electronics

Description: The ICL3221EM and ICL3221EF devices are 3. 3V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V. 28/V. 24 specifications. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Efficient on-chip charge pumps, coupled with manual and 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 sp
