ISL4260E
QFN Packaged,
±15kV ESD Protected, +3V
to +5.5V, 150nA, 250kbps, RS-232
Transmitters/Receivers with Separate
Logic Supply
The ISL4260E 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. Targeted
applications are PDAs, Palmtops, and cell phones where the
low operational, and even lower standby, power
consumption is critical. Efficient on-chip charge pumps,
coupled with a manual powerdown function reduces the
standby supply current to a 150nA trickle. Tiny 5mm x 5mm
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.
The ISL4260E features a VL pin that adjusts the logic pin
(see Pin Descriptions table) output levels and input
thresholds to values compatible with the VCC powering the
external logic (e.g., a UART).
The single pin powerdown function (SHDN = 0) disables all
the receiver and transmitter outputs, while shutting down the
charge pump to minimize supply current drain.
Table 1 summarizes the features of the ISL4260E, while
Application Note AN9863 summarizes the features of each
device comprising the 3V RS-232 family.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish,
which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
