FN4900.9
±15kV ESD Protected, +3V to +5.5V,
1Microamp, 1Mbps, 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 VCC = 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 1µA 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 ICL3245E is a 3 driver, 5 receiver device that provides a
complete serial port suitable for laptop or notebook
www.DataSheet4U.cocmomputers. 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
ICL32XXE 3V family.
