Data Sheet

April 13, 2007

FN6045.2

QFN Packaged, ±15kV ESD Protected,

+2.7V to +5.5V, 150nA, 250kBps, RS-232

Transmitters/Receivers

Features

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

which is 40% Smaller than a 20 Lead TSSOP

The Intersil ISL422XE devices are 2.7V to 5.5V powered

RS-232 transmitters/receivers which meet ElA/TIA-232 and

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

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

V.28/V.24 specifications, even at V

= 3.0V. Additionally,

they provide ±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 hand-held products where the low

operational, and even lower standby, power consumption is

critical. Efficient on-chip charge pumps, coupled with manual

and automatic powerdown functions, reduce the standby

supply current to a 150nA 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.

• RS-232 Compatible with V

= 2.7V

• On-Chip Voltage Converters Require Only Four External

0.1μF Capacitors

• Manual and Automatic Powerdown Features

• Receiver Hysteresis For Improved Noise Immunity

• Guaranteed Minimum Data Rate . . . . . . . . . . . . 250kBps

• Wide Power Supply Range . . . . . . Single +2.7V to +5.5V

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

• Pb-Free Plus Anneal Available (RoHS Compliant)

The ISL4221E is a 1 driver, 1 receiver device and the

ISL4223E is a 2 driver, 2 receiver device that, coupled with

the 5mmx5mm QFN package, provide the industry’s

smallest, lowest power serial port suitable for PDAs, and

hand-held applications. The 5mmx5mm QFN requires 40%

less board area than a 20 lead TSSOP, and is nearly 20%

thinner.

Applications

• Any Space Constrained System Requiring RS-232 Ports

- Battery Powered, and Portable Equipment

- Hand-Held Products (GPS Receivers, Bar Code

Scanners, etc.)

- PDAs and Palmtops, Data Cables

- Cellular/Mobile Phones, Digital Cameras

The ISL422XE features an automatic powerdown function

that powers down the on-chip power-supply and driver

circuits. This occurs when an attached peripheral device is

shut off or the RS-232 cable is removed, conserving system

power automatically without changes to the hardware or

operating system. It powers up again when a valid RS-232

voltage is applied to any receiver input.
