Features
• Pb-Free Available as an Option (see Ordering Info)
• ESD Protection for RS-232 I/O Pins to ±15kV (IEC61000)
The Intersil ICL32X7E devices are 3V to 5.5V powered
RS-232 transmitters (five)/receivers (three) which meet
ElA/TIA-232 and V.28/V.24 specifications, even at

protection (IEC61000-4-2 Air Gap) and ±15kV Human Body
Model protection on transmitter outputs and receiver inputs
(RS-232 pins). Targeted applications are ISDN Terminal
Adaptors, PDAs, Palmtops, peripherals, and notebook and
laptop computers where the low operational, and even lower
standby, power consumption is critical. The ICL3217E’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 5V systems, and
5V-only systems, and is a lower power, pin-for-pin

The ICL3217E 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 ICL3217E powers up again when a
valid RS-232 voltage is applied to any receiver input.
