The size of R1 is a tradeoff between the OUT rise time and the current when OUT is pulled low. A lower current is generally better, however faster transitions and bandwidth require a smaller resistor for faster switching.
In addition, make sure that the value of R1 > 500 Ω so that the output driver can pull the OUT pin close to GND.
Vref is not restricted to VCC. The allowable voltage range of this pin is specified in the Absolute Maximum Ratings.
Select a value for C2 based on the system bandwidth specifications as shown in Equation 2.
