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: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
