QFN Packaged, ±15kV ESD Protected,
+2.7V to +5.5V, 10Nanoamp, 250kbps,
RS-232 Transmitters/Receivers
The Intersil ISL424XE devices are 2.7V to 5.5V powered
RS-232 transmitters/receivers 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 Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are PDAs,
Palmtops, and notebook and laptop computers where the
low operational, and even lower standby, power consumption
is critical. Efficient on-chip charge pumps, coupled with
manual and automatic powerdown functions, reduce the
standby supply current to a 10nA trickle. Tiny 5mm x 5mm
Quad Flat No-Lead
(QFN) 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.
The ISL424XE are 3 driver, 5 receiver devices that, coupled
with the 5x5 QFN package, provide the industry’s smallest,
lowest power complete serial port suitable for PDAs, and
laptop or notebook computers. The 5x5 QFN requires 60%
less board area than a 28 lead TSSOP, and is nearly 20%
thinner. The devices also include a noninverting always-
active receiver for “wake-up” capability.
The
ISL4243E
features an
automatic powerdown
function
that 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. It powers up again when a valid RS-232
voltage is applied to any receiver input.
Table 1 summarizes the features of the ISL424XE, while
Application Note AN9863 summarizes the features of each
device comprising the 3V RS-232 family.
