ICL3224E, ICL3226E, ICL3244E
+/-15kV ESD Protected, +3V to +5.5V,
1Microamp, 250kbps, RS-232
Transceivers with Enhanced Automatic
Powerdown
The Intersil ICL32XXE devices are 3.0V 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 enhanced automatic powerdown
functions, reduce the standby supply current to a 1
μ
A 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 5.0V systems, and 5.0V only
systems.
The ICL3244E is a 3 driver, 5 receiver device that provides a
complete serial port suitable for laptop or notebook
computers. It also includes a noninverting always-active
receiver for “wake-up” capability.
These devices, feature an
enhanced automatic
powerdown
function which powers down the on-chip power-
supply and driver circuits. This occurs when all receiver and
transmitter inputs detect no signal transitions for a period of
30 seconds. These devices power back up, automatically,
whenever they sense a transition on any transmitter or
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.
