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

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.

(see Pin Descriptions table) output levels and input

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.

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.
