ICL3237E
±15kV ESD Protected, 10nA Supply-Current, +3V to +5.5V, 250k/1Mbps, RS-232 Transmitters/Receivers
The ICL3237E contains 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. It provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are cell phones, PDAs, Palmtops, and notebook and laptop computers where the low operational power and even lower standby power consumption is critical. Efficient on-chip charge pumps coupled with the manual powerdown function reduce the standby supply current to a 10nA trickle. Small footprint packaging and the use of small, low value capacitors ensure board space savings.
