ICL3207E
±15kV ESD Protected, +3V to +5.5V, Low Power, 250kbps, RS-232
Transmitter/Receiver
The
ICL3207E
is a 3V to 5.5V powered RS-232
transmitter/receiver that meets ElA/TIA-232 and
V.28/V.24 specifications, even at V
CC
= 3.0V. The
ICL3207E features five transmitters and
three receivers. It provides ±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 Adapters (TAs), PDAs, Palmtops,
peripherals, and notebook and laptop computers
where the low operational power consumption and
even lower standby power consumption is critical.
Small footprint packaging and the use of small, low
value capacitors ensure board space savings. Data
rates greater than 250kbps are ensured at worst case
load conditions. The ICL3207E is fully compatible with
3.3V only systems, mixed 3.3V and 5V systems, and
5V only systems. The ICL3207E is a lower power,
pin-for-pin replacement for the MAX207E, HIN207E,
and HIN237E.
Table 1
summarizes the features of the ICL3207E.
AN9863
summarizes the features of each device in
the ICL32xxE 3V family.
Features
• Pb-free (RoHS compliant)
• ESD protection for RS-232 I/O pins to ±15kV
(IEC61000)
• 5V lower power replacement for MAX207E,
HIN207E, and HIN237E
• Meets EIA/TIA-232 and V.28/V.24 specifications
at 3V

• On-chip voltage converters require only four
external 0.1µF capacitors
• RS-232 compatible with V
CC
= 2.7V

Notes:
1. See
TB347
for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which is compatible with both SnPb and Pb-free soldering operations. 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.
3. For Moisture Sensitivity Level (MSL), see the
ICL3207E
device page. For more information about MSL, see
