Transmitters/Receivers  
Features  
• ESD Protection for RS-232 I/O Pins to ±15kV (IEC1000)  
• Drop in Replacement for SP3220E  
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  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• Interoperable with RS-232 down to V  
• Latch-Up Free

±15kV ESD protection (IEC 1000-4-2 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.  
• On-Chip Voltage Converters Require Only Four External  
0.1µF Capacitors  
• Manual Powerdown Feature with Receivers Active  
• Separate Receiver Enable Pin  
• R and T Hysteresis For Improved Noise Immunity
