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.
