±15kV ESD Protected, +3V to +5.5V,

1 Microamp, 250Kbps, RS-232

Transmitter/Receiver

The Intersil ISL83384E 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 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

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. This device is fully compatible with 3.3V only

systems, mixed 3.3V and 5.0V systems, and 5.0V only

systems.

The single pin powerdown function (SHDN = 0) disables all

the transmitters and receivers, while shutting down the

charge pump to minimize supply current drain.

Table 1 summarizes the features of the ISL83384E, while

Application Note AN9863 summarizes the features of each

device comprising the ICL32XX 3V family.
