Data Sheet
April 2003
FN6017.1
鹵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
CC
= 3.0V. 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
reduces the standby supply current to a 1碌A(chǔ) 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.
