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 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 250kbps are ensured at worst case load conditions. These devices are fully compatible with 3.3V-only systems.
