ISL3232E, ISL4221E, ISL4223E
QFN Packaged, ±15kV ESD Protected, +2.7V to +5.5V, 150nA, 250kbps,
RS-232 Transmitters/Receivers
The
ISL3232E, ISL4221E,
and
ISL4223E
devices are
2.7V to 5.5V powered RS-232 transmitters/receivers
that meet ElA/TIA-232 and V.28/V.24 specifications,
even at V
CC
= 3.0V. They provide ±15kV ESD
protection (IEC61000-4-2 Air Gap and Human Body
Model) on transmitter outputs and receiver inputs
(RS-232 pins). Targeted applications are PDAs,
Palmtops, and hand-held products where the low
operational power consumption and even lower
standby power consumption are critical. Efficient
on-chip charge pumps, coupled with manual and
automatic powerdown functions, reduce the standby
supply current to a 150nA trickle. The 5mmx5mm
Quad Flat No-Lead (QFN) 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 ISL4221E is a 1 driver, 1 receiver device and the
ISL3232E and ISL4223E are 2 driver, 2 receiver
devices that, coupled with the 5mmx5mm QFN
package, provide the industry’s smallest, lowest
power serial port suitable for PDAs, and hand-held
applications. The 5mmx5mm QFN requires 40% less
board area than a 20 Ld TSSOP, and is nearly 20%
thinner.
The ISL4221E and ISL4223E versions feature an
automatic powerdown function that powers down the
on-chip power supply and driver circuits. Automatic
powerdown occurs when an attached peripheral
device is shut off or the RS-232 cable is removed, and
conserves system power automatically without
changes to the hardware or operating system. The
ISL4221E and ISL4223E power back up automatically
when a valid RS-232 voltage is applied to any
receiver input.

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 plus anneal (e3 termination finish, which is RoHS compliant and 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
ISL3232E, ISL4221E,
