3 / 7 page 3 www.fairchildsemi.com AC Electrical Characteristics Note 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) + (ICCstatic). Dynamic Switching Characteristics AC Loading and Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz; t W = 500 ns FIGURE 1. AC Test Circuit Application Note: When operating the NC7NZU04’s unbuffered output stage in its linear range, as in oscillator applications, care must be taken to observe maximum power rating for the device and package. The high drive nature of the design of the output stage will result in substantial simulta- neous conduction currents when the stage is in the linear region. See the ICCPEAK specification in the DC Electrical Characteristics table. Input = AC Waveform; t r = tf = 1.8 ns; PRR = variable; Duty Cycle = 50% FIGURE 2. ICCD Test Circuit FIGURE 3.
