Low Power, +3V to +5.5V, 250kbps ,  
RS-232 Trans mitters /Receivers  
Features  
• Pb-free Available as an Option (see Ordering Info)  
The Intersil ICL32X7 devices are 3.0V to 5.5V powered  
RS-232 transmitters (five)/receivers (three) which meet  
ElA/TIA-232 and V.28/V.24 specifications, even at  
±15kV ESD Protected (Human Body Model)  
• 5V Lower Power Replacement for MAX207, HIN207,  
HIN237  
V
= 3.0V. Targeted applications are ISDN Terminal  
CC  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• Latch-Up Free  
Adaptors, PDAs, Palmtops, peripherals, and notebook and  
laptop computers where the low operational, and even lower  
standby, power consumption is critical. The ICL3217’s  
efficient on-chip charge pumps, coupled with an automatic  
powerdown function, reduces 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. This family is fully compatible  
with 3.3V only systems, mixed 3.3V and 5.0V systems, and  
5.0V only systems, and is a lower power, pin-for-pin  
replacement for ‘207 and ‘237 type devices.  
• On-Chip Voltage Converters Require Only Four External  
0.1µF Capacitors  
• Automatic Powerdown (I  
CC  
= 1µA, ICL3217 Only)  
• Receiver Hysteresis For Improved Noise Immunity  
• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps  
• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/µs  
• Wide Power Supply Range . . . . . . . Single +3V to +5.5V  
Applications  
• Any System Requiring RS-232 Communication Ports  
- Battery Powered, Hand-Held, and Portable Equipment  
- Laptop Computers, Notebooks, Palmtops  
The ICL3217 features an automatic powerdown 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. The ICL3217 powers up again when a  
valid RS-232 voltage is applied to any receiver input.  
- Modems, Printers and other Peripherals  
- ISDN Terminal Adaptors and Set Top Boxes
