Datasheet ISL4270E QFN Packaged, ±15kV ESD Protected, +3V to +5.5V, 300nA, 250kbps, RS-232 Transceivers with Enhanced Automatic Powerdown and a Separate Logic Supply The ISL4270E is a 3.0V to 5.5V powered RS-232 transceiver that meets 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 notebook and laptop computers 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 300nA trickle.
