Data Sheet

October 21, 2005

FN6003.3

1 Microamp Supply-Current, +3V to +5.5V,

1Mbps , RS-232 Trans mitters /Receivers

Features

• ±15kV ESD Protected (Human Body Model)

The Intersil ICL3237 contains 3.0V to 5.5V powered RS-232

transmitters/receivers which meet ElA/TIA-232 and

• Drop in Replacement for MAX3237

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

• Latch-Up Free

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

= 3.0V. Targeted

applications are cell phones, 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 powerdown

function, 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

• On-Chip Voltage Converters Require Only Four External

Capacitors

• Manual Powerdown Features

• Flow Through Pinout

• Receiver Hysteresis For Improved Noise Immunity

• Pin Selectable Data Rate

greater than 1Mbps (MBAUD = V ) are guaranteed at

worst case load conditions. This family is fully compatible

with 3.3V only systems, mixed 3.3V and 5.0V systems, and

5.0V only systems.

• Guaranteed Minimum Data Rate . . . . . . . 250kbps/1Mbps

• Guaranteed Minimum Slew Rate . . . . . . . 6V/µs or 24V/µs

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

• Low Supply Current in Powerdown State. . . . . . . . . . .1µA

• Pb-Free Plus Anneal Available (RoHS Compliant)

The ICL3237 is a 5 driver, 3 receiver device that also

includes a noninverting always-active receiver for “wake-up”

capability.

Table 1 summarizes the features of the device represented

by this data sheet, while Application Note AN9863

summarizes the features of each device comprising the

ICL32XX 3V family.

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

- Cellular/Mobile Phone
