Transmitters/Receivers
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 automatic powerdown functions
(except for the ICL3232E), 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 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 ICL324XE are 3-driver, 5-receiver devices that provide a
complete serial port suitable for laptop or notebook
computers. Both devices also include noninverting
always-active receivers for “wake-up” capability.
The
ICL3221E, ICL3223E and ICL3243E,
feature an
automatic powerdown
function which 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. These
devices power up again when a valid RS-232 voltage is
applied to any 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.
