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 В±15kV ESD
protection (IEC61000-4-2 Air Gap and Human Body
Model) on transmitter outputs and receiver inputs (RS232 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 power-down
functions (except for the ICL3232E), reduce the
standby supply current to a 1ВµA 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 3.3Vonly 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 …
