10.2.2.1 Slope Control

Adjust the rise and fall slope of the SN55HVD233-SEP driver output by connecting a resistor from the RS (pin 8) to ground (GND), or to a low-level input voltage as shown in Figure 30.

The slope of the driver output signal is proportional to the pin's output current. This slope control is implemented with an external resistor value ranging from 0 Ω to achieve a ≈38-V/µs single ended slew rate, and up to 50 kΩ to achieve a ≈4-V/µs slew rate as displayed in Figure 31. Figure 32 shows typical driver output waveforms with slope control.
