ISL83386E
±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 VCC = 3.0V. Targeted
applications are PDAs, Palmtops, and cell phones where the
low operational, and even lower standby, power consumption
is critical. Efficient on-chip charge pumps, coupled with a
manual powerdown function reduces the standby supply
current to a 1
µA 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 VL pin that adjusts the logic pin
(see Pin Descriptions table) output levels and input
thresholds to values compatible with the VCC powering the
external logic (e.g., a UART).
The single pin powerdown function (SHDN = 0) disables all
the receiver and transmitter outputs, while shutting down the
charge pump to minimize supply current drain.
Table 1 summarizes the features of the ISL83386E, while
Application Note AN9863 summarizes the features of each
device comprising the 3V RS-232 family.
