Data Sheet

July 2004

FN6014.2

±15kV ESD Protected, 10nA Supply-

Current, +3V to +5.5V, 250k/1Mbps,

RS-232 Transmitters/Receivers

Features

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

• Pin Compatible Replacement for MAX3237E

The Intersil ICL3237E contains 3.0V to 5.5V powered

• Pin Selectable, Guaranteed Data Rate . . 250kbps/1Mbps

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

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

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

= 3.0V. Additionally, it

provides ±15kV ESD protection (IEC61000-4-2 Air Gap and

Human Body Model) on transmitter outputs and receiver

inputs (RS-232 pins). Targeted applications are cell phones,

PDAs, Palmtops, and notebook and laptop computers where

the low operational, and even lower standby, power

• RS-232 Compatible with V

• Latch-Up Free

= 2.7V

• On-Chip Voltage Converters Require Only Four External

Capacitors

consumption is critical. Efficient on-chip charge pumps,

coupled with the manual powerdown function, reduce the

standby supply current to a 10nA trickle. Small footprint

packaging, and the use of small, low value capacitors ensure

board space savings as well. Data rates greater than 1Mbps

• Manual Powerdown Feature

• Flow Through Pinout

• Rx and Tx Hysteresis For Improved Noise Immunity

• Rx Active in Powerdown; Separate Rx Enable Pin

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

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

• Low Supply Current in Powerdown State. . . . . . . . . .10nA

• Pb-free available

(MBAUD = V ) are guaranteed at worst case load

conditions. The ICL3237E is fully compatible with 3.3V only

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

systems.

The ICL3237E is a 5 driver, 3 receiver device that also

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

capability.

Applications
