ICL3221EF RS-232 Transmitters/Receivers

Datasheet ICL3221EM, ICL3221EF ±15kV ESD Protected, +3.3V, 1µA, 250kbps, RS-232 Transmitters/Receivers 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 supp.
