ICL3207E, ICL3217E
Data Sheet
June 2004
FN4914.5
+/- 15kV ESD Protected, +3V to +5.5V, Low
Power, 250kbps, RS-232
Transmitters/Receivers
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
V
CC
= 3.0V. Additionally, they provide
±
15kV ESD
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
replacement for ‘207E and ‘237E type devices.
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.
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
ICL32XXE 3V family.
Features
• Pb-Free Available as an Option (see Ordering Info)

HIN237E
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V
• Latch-Up Free
• On-Chip Voltage Converters Require Only Four External
0.1µF Capacitors
• RS-232 Compatible with V
CC
= 2.7V
• Automatic Powerdown (I
CC
= 1µA, ICL3217E Only)
• Receiver Hysteresis For Improved Noise Immunity
• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps
• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/µs
