ISL83220E
Data Sheet
April 27, 2006
FN6011.5
±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 V
CC
= 3.0V. Additionally, 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 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 1μA 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.
Table 1 summarizes the features of the ISL83320E, while
Application Note AN9863 summarizes the features of each
device comprising the ICL32XXE 3V family.
Features
• Pb-Free Plus Anneal Available (RoHS Compliant)

• RS-232 Compatible Outputs at 2.7V
• Latch-Up Free
• On-Chip Voltage Converters Require Only Four External
0.1μF Capacitors
• Manual Powerdown Feature with Receivers Active
• Separate Receiver Enable Pin
• R

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
