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.
