ISL83239E
TM
Data Sheet
September 2001
File Number
6015.1
鹵15kV
ESD Protected, 10nA Supply-
Current, +3V to +5.5V, 250kbps, RS-232
Transmitters/Receivers
The Intersil ISL83239E 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. Additionally, it
provides
鹵
15kV ESD protection (IEC 1000-4-2 Air Gap and
Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are cell phones,
PDAs, Palmtops, and data cables where the low operational,
and even lower standby, power consumption is critical.
Efficient on-chip charge pumps, coupled with the manual
powerdown function, reduce the standby supply current to a
10nA 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 ISL83239E is a 5 driver, 3 receiver device that also
includes a noninverting always-active receiver for 鈥渨ake-up鈥?/div>
capability.
Table 1 summarizes the features of the device represented
by this data sheet, while Application Note AN9863
summarizes the features of each device comprising the
ICL32XX 3V family.
