+/-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
±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.
Table 1 summarizes the features of the ISL83320E, while

Power Supply Decoupling
In most circumstances a 0.1µF bypass capacitor is
adequate. In applications that are particularly sensitive to
power supply noise, decouple VCC to ground with a
capacitor of the same value as the charge-pump capacitor C1.
Connect the bypass capacitor as close as possible to the IC.
Transmitter Output when Exiting
Powerdown
Figure 3 shows the response of the transmitter output when
exiting powerdown mode. As it activates, the transmitter
output properly goes to RS-232 levels, with no glitching,
ringing, nor undesirable transients. The transmitter is loaded
with 3kin parallel with 2500pF. Note that the transmitter
enables only when the magnitude of the supplies exceed
approximately 3V.

High Data Rates
The ISL83220E maintains the RS-232 ±5V minimum
transmitter output voltages even at high data rates. Figure 4
details a transmitter loopback test circuit, and Figure 5
illustrates the loopback test result at 120kbps. For this test,
the transmitter is driving an RS-232 load in parallel with
1000pF, at 120kbps. Figure 6 shows the loopback results for
the transmitter driving 1000pF and an RS-232 load at
250kbps.
