Pin Descriptions
Note 1:Internal pull-up resistor of nomimally 100K to 120K at 3.3V on indicated inputs.
Note 2: The PD# input pin has a protection diode clamp to the VDDL power supply. If VDDL is not connected to VDD, (ie
VDDL=2.5V, VDD=3.3V) then this input must have a series resistor if the logic high is connected to VDD. This input
series resistor provides current limit for the clamp diode. For a pullup to VDD it should be 1Kohm or more from the PD#
pin to VDD. If the PD# pin is being driven by logic powered by 3.3V, then a 100 series resistor will be suffcient.
