ICL3224E, ICL3226E, ICL3244E
+/-15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232
Transceivers with Enhanced Automatic Powerdown
The Intersil ICL32XXE devices are 3.0V to 5.5V powered
RS-232 transmitters/receivers which meet ElA/TIA-232
and V.28/V.24 specifications, even at VCC = 3.0V.
Additionally, they provide п‚±15kV ESD protection
(IEC61000-4-2 Air Gap and Human Body Model) on
transmitter outputs and receiver inputs (RS-232 pins).
Targeted applications are PDAs, Palmtops, and notebook
and laptop computers where the low operational, 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 1пЃA trickle. Small footprint
packaging, and the use of small, low value capacitors
ensure board space savings as well. Data rates greater
than 250kbps are guaranteed at worst case load
conditions. This family is fully compatible with 3.3V only
systems, mixed 3.3V and 5.0V systems, and 5.0V only
systems. FN4899
