1 Microamp, +3V to +5.5V, 1Mbps, RS-232
Transceivers with Enhanced Automatic
Powerdown
The Intersil ICL32XX 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 VCC = 3.0V. 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
A trickle. Small footprint packaging, and the
use of small, low value capacitors ensure board space
savings as well. Data rates greater than 1Mbps 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 ICL3245 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
30s. These devices power back up, automatically, whenever
they sense a transition on any transmitter or receiver input.
Table 1 summarizes the features of the device represented
by this data sheet, while Application Note AN9863
summarizes the features of each device comprising the
ICL32XX 3V family.
