ADG3304 and ADG3308 is same architecture device, I believe.
I found different description in datasheet.
ADG3304 data sheet requests lower output impedance <=150ohm / 36mA peak current capability for output driver.
ADG3308 data sheet doesn't have this description.
ADG3304/8 can drive about 1mA, I think.
For example .
Vlow th= 5X0.35= 1.75V
When Input level goes to below 1.75V, then change the output, I think.
1. Does ADG3308 inputs need 36mA peak current capability driver?
2. How come these requirements ,36mA and 150ohm ?
