Absolute Maximum Ratings

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:

4. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (I

CCD

) at no output loading and operating at 50% duty cycle (see Figure 2). CPD is related to I

CCD

dynamic operating current by

the expression: I

CCD

= (CPD)(VCC)(fIN) + (ICC static).
