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 t he total power dissipation below absolute maximum ratings and the sign is used to indicate direction. 3: Test conditions are those specifie d by TIA/EIA232-F and as listed above.

UNISONIC TECHNOLOGIES CO., LTD 7 of 10 www.unisonic.com.tw QW-R113-005,D APPLICATION INFORMATION Power-Supply protection to meet Power-Off fault conditions of TIA/EIA-232-F Diodes placed in series with the V DD and V SS 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. UTC 75232 UTC 75232 VDD VSS VDD VSS Output ±15V 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.
