Note. 1. For voltage logic levels, the more positive (less negative) limit is designated as maximum, (e.g. if -10V is a  
maximum, the typical value is a more negative voltage).  
2: Output short circuit conditions must maintain the total power dissipation below absolute maximum ratings  
and the sign is used to indicate direction.  
3: Test conditions are those specified by TIA/EIA232-F and as listed above.

APPLICATION INFORMATION  
Power-Supply protection to meet Power-Off fault conditions of TIA/EIA-232-F  
Diodes placed in series with the VDD and VSS leads protect the device in the fault condition in which the  
device outputs are shorted to ±15V and the power supplies are at low and provide low-impedance paths to  
ground.

Typical Connection  
“*”: Refer Figure 10 to select the correct values for the loading capacitors (C1, C2, and C3), which are required to  
meet the RS-232 maximum slew-rate requirement of 30V/μs. The value of the loading capacitors required  
depends upon the line length and desired slew rate, but typically is 330 pF.
