10.3.3 Slope Control
The rise and fall slope of the SN65HVD233, SN65HVD234, and SN65HVD235 driver output can be adjusted by connecting a resistor from the Rs (pin 8) to ground (GND), or to a low-level input voltage as shown in Figure 32.
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 of 10 kΩ to achieve a ~15 V/μs slew rate, and up to 100 kΩ to achieve a ~2.0 V/μs slew rate . A typical slew rate verses pulldown resistance graph is shown in Figure 33. Typical driver output waveforms with slope control are displayed in Figure 39.
