±15kV ESD Protected, +3V, 1µA, 250kbps, RS-232

Transmitters/Receivers

ICL3221EM

Features

The Intersil ICL3221EM devices are 3.0V powered RS-232

transmitters/receivers which meet ElA/TIA-232 and

V.28/V.24 specifications. 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

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 1µA trickle. Small footprint 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 device is fully

compatible with 3.3V-only systems.

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

(IEC61000)

• Drop in Replacement for MAX3221E

• RS-232 Compatible with V = 2.7V

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

• Latch-Up Free

• On-Chip Voltage Converters Require Only Four External

0.1µF Capacitors

• Manual and Automatic Power-down Features

• Receiver Hysteresis For Improved Noise Immunity

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

• Power Supply Range. . . . . . . Single +3.0V to +3.6V

• Low Supply Current in Power-down State. . . . . . 1µA

• Pb-Free (RoHS Compliant)

The ICL3221EM features an automatic power-down

function which 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.

These devices power up again when a valid RS-232

voltage is applied to any receiver input.

Applications

• Any System Requiring RS-232 Communication Ports

- Battery Powered, Hand-Held, and Portable

Equipment

- Laptop Computers, Notebooks, Palmtops

- Modems, Printers and other Peripherals

- Digital Cameras

1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.

2. 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.

3. For Moisture Sensitivity Level (MSL), please see device information page for ICL3221EM. For more information on MSL please

see techbrief TB363.
