Is a pull down resistor needed here?

Hi
I was reading the datasheet for this part (FAN73832) and I found in the logic characteristics section something about 100K ohm input pull down resistor.
does that mean I have to connect a 100k Ohm resistor between the input pin and the ground pin?
my input is 5V TTL PWM signal supplied by a signal generator.

Thank you for your help. FAN73832 circuit.jpgFAN73832 specs.jpgFAN73832 diagram.jpgView attachment FAN73832.pdf
 

It means that it already has a 100k pulldown internally - as shown in the block diagram figure 3.

(one other clue is the Iin+ bias current of typically 50uA at 5V = 100k ohms).
