ISL83386E
Data Sheet November 19, 2004
±15kV ESD Protected, +3V to +5.5V,
1 Microamp, 250kbps, RS-232
Transmitters/Receivers with Separate
Logic Supply
The ISL83386E contains 3.0V to 5.5V powered RS-232
transmitters/receivers which meet ElA/TIA-232 and
V.28/V.24 specifications, even at V
applications are PDAs, Palmtops , and cell phones where the
low operational, and even lower standb y, power consumption
is critical. Efficient on-chip charge pumps, coupled with a
manual powerdown function reduces 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.
The ISL83386E features a V
pin that adjusts the logic pin
L
(see Pin Descriptions table) output levels and input
thresholds to values compatible with the V
external logic (e.g., a UART).

the receiver and transmitter outputs, while shutting down the
charge pump to minimize supply current drain.

NOTE: Intersil Pb-free 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-020C.
