+3V to +5.5V, 1 Microamp, 250kbps ,  
RS-232 Trans mitter/Receiver  
Features  
±15kV ESD Protected (Human Body Model)  
The Intersil ICL3310 contains 3.0V to 5.5V powered RS-232  
transmitters/receivers which meet ElA/TIA-232 and  
• Low Power, Pin Compatible Upgrade for 5V MAX222,  
SP310A, and LT1X80/A  
V.28/V.24 specifications, even at V  
= 3.0V. Targeted  
CC  
• Single SHDN Pin Disables Transmitters and Receivers  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• Latch-Up Free  
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 a manual 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 device is fully compatible with 3.3V only  
systems, mixed 3.3V and 5.0V systems, and 5.0V only  
systems.  
• On-Chip Voltage Converters Require Only Four External  
0.1µF Capacitors  
• Receiver Hysteresis For Improved Noise Immunity  
• Very Low Supply Current . . . . . . . . . . . . . . . . . . . . 0.3mA  
• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps  
• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/µs  
• Wide Power Supply Range . . . . . . . Single +3V to +5.5V  
• Low Supply Current in Powerdown State. . . . . . . . . .<1µA  
The single pin powerdown function (SHDN = 0) disables all  
the transmitters and receivers, while shutting down the  
charge pump to minimize supply current drain.  
Table 1 summarizes the features of the ICL3310, while  
Application Note AN9863 summarizes the features of each  
device comprising the ICL32XX 3V family.
