ISL83220E
Rev X.00 В±15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232
Transmitters/Receivers
The Intersil ISL83220E is a 3.0V to 5.5V powered RS-232
transmitter/receiver which meets ElA/TIA-232 and V.28/V.24
specifications, even at VCC = 3.0V. Additionally, it provides
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 a
manual powerdown function, 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.
