Data Sheet

FN6035.1

QFN Packaged, ±15kV ESD Protected, +3V

to +5.5V, 150nA, 250kbps, RS-232

Transmitters/Receivers with Separate

Logic Supply

Features

• Available in Near Chip Scale QFN (5mmx5mm) Package

• V Pin for Compatibility with Mixed Voltage Systems

• ESD Protection for RS-232 I/O Pins to ±15kV (IEC61000)

• Single SHDN Pin Disables Transmitters and Receivers

• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V

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 V

= 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.

• On-Chip Charge Pumps Require Only Four External

0.1µF Capacitors

• Receiver Hysteresis For Improved Noise Immunity

• Very Low Supply Current . . . . . . . . . . . . . . . . . . . . 300µA

• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps

• Wide Power Supply Range. . . . . . . . Single +3V to +5.5V

• Low Supply Current in Powerdown State. . . . . . . . .150nA

• Pb-free available

The ISL4260E features a V pin that adjusts the logic pin

(see Pin Descriptions table) output levels and input

thresholds to values compatible with the V

external logic (e.g., a UART).

Applications

• Any System Requiring RS-232 Communication Ports

- Battery Powered, Hand-Held, and Portable Equipment

- Laptop Computers, Notebooks, Palmtops

- Digital Cameras

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.

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.
