ISL4270E Description
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 notebook and laptop puters where the low operational power consumption and even lower standby power consumption is critical. Efficient on-chip charge-pumps coupled with manual and enhanced automatic powerdown functions reduce the standby supply current to a...
