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  
CC  
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

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

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  
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.  
• Any System Requiring RS-232 Communication Ports  
- Battery Powered, Hand-Held, and Portable Equipment  
- Laptop Computers, Notebooks, Palmtops  
- Modems, Printers and other Peripherals  
- Data Cradles and Cables  
- Cellular/Mobile Phone
