Note:
Absolute maximum ratings are DC values beyond which the
device may be damaged or have its useful life impaired. The
datasheet specifications should be met, without exception,
to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables.
Pericom does not recommend operation outside datasheet
specifications.

Notes:
3. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption
(ICCD) at no output loading and operating at 50% duty cycle (see Figure 2). CPD is related to ICCD dynamic operating current by
the expression: ICCD = (CPD)(VCC)(fIN) + (ICC static).
