VDD ±15V Output UTC 75232 VDD UTC 75232 VSS VSS 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.
