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.

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). 3 PS8519C 08/08/01 PI74ST1G79 SOTiny Gate ST Single Positive-Edge-Triggered D-Type Flip-Flop 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 AC Loading and Waveforms VCC VCC A CLK QOUT DIN CL CLK RL QOUT DIN CL includes load and stray capacitance Input PRR = 1.0 MHz; tW = 500ns Input = AC Waveform; tr = tf = 1.8ns; PRR = 10 MHz; Duty Cycle = 50% Figure 1.
