DATASHEET
ISL4241E, ISL4243E FN8037
Rev 7.00
Jun 10, 2010 QFN Packaged, В±15kV ESD Protected, +2.7V to +5.5V, 10Nanoamp, 250kbps,
RS-232 Transmitters/Receivers
Intersil’s ISL4241E, ISL4243E devices are 2.7V 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 automatic
power-down functions, reduce the standby supply current to
a 10nA trickle. Tiny 5mmx5mm Quad Flat No-Lead (QFN)
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. Features The ISL4241E, ISL4243E’s are 3 driver, 5 receiver devices
that, coupled with the 5x5 QFN package, provide the
industry’s smallest, lowest power complete serial port
suitable for PDAs, and laptop or notebook computers. The …
