ICL3237E
Data Sheet
July 2004
FN6014.2
鹵15kV
ESD Protected, 10nA Supply-
Current, +3V to +5.5V, 250k/1Mbps,
RS-232 Transmitters/Receivers
The Intersil ICL3237E 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 (IEC61000-4-2 Air Gap and
Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are cell phones,
PDAs, Palmtops, and notebook and laptop computers 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 1Mbps
(MBAUD = V
CC
) are guaranteed at worst case load
conditions. The ICL3237E is fully compatible with 3.3V only
systems, mixed 3.3V and 5.0V systems, and 5.0V only
systems.
The ICL3237E 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.
