Data Sheet October 20, 2005

Low Power, +3V to +5.5V, 250kbps,
RS-232 Transmitters/Receivers

The Intersil ICL32X7 devices are 3.0V to 5.5V powered
RS-232 transmitters (five)/receivers (three) which meet
ElA/TIA-232 and V.28/V.24 specifications, even at
V

= 3.0V. Targeted applications are ISDN Terminal

CC

Adaptors, PDAs, Palmtops, peripherals, and notebook and
laptop computers where the low operational, and even lower
standby, power consumption is critical. The ICL3217’s
efficient on-chip charge pumps, coupled with an automatic
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 family is fully compatible
with 3.3V only systems, mixed 3.3V and 5.0V systems, and

5.0V only systems, and is a lower power, pin-for-pin
replacement for ‘207 and ‘237 type devices.

The ICL3217 features an automatic powerdown function
which powers down the on-chip power-supply and driver
circuits. This occurs when an attached peripheral device is
shut off or the RS-232 cable is removed, conserving system
power automatically, without changes to the hardware or
operating system. The ICL3217 powers up again when a
valid RS-232 voltage is applied to any receiver input.

Table 1 summarizes the features of the devices represented
by this data sheet, while application Note AN9863
summarizes the features of each device comprising the
ICL32XX 3V family.

NOTE: Intersil Pb-free plus anneal 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-020.
