Rev 12.00
December 12, 2016 В±15kV ESD Protected, +3V to +5.5V, 1ВµA, 1Mbps, RS-232 Transceivers with
Enhanced Automatic Powerdown
The Intersil ICL3225E, ICL3227E, and ICL3245E 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 (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 1ВµA 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. Features The ICL3245E is a 3-driver, 5-receiver device that provides a
complete serial port suitable for laptop or notebook …
