ICL3237E FN6014
Rev 2.00
July 2004 В±15kV ESD Protected, 10nA Supply-Current, +3V to +5.5V, 250k/1Mbps, RS-232
Transmitters/Receivers
The Intersil ICL3237E contains 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, it
provides п‚±15kV ESD protection (IEC61000-4-2 Air Gap and
Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are cell phones,
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 the manual powerdown function, reduce the
standby supply current to a 10nA trickle. Small footprint
packaging, and the use of small, low value capacitors
ensure board space savings as well. Data rates greater than
1Mbps (MBAUD = VCC) are guaranteed at worst case load
conditions. The ICL3237E is fully compatible with 3.3V only
systems, mixed 3.3V and 5.0V systems, and 5.0V only
systems.
The ICL3237E is a 5 driver, 3 receiver device that also …
