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). AC Loading and Waveforms Figure 1. AC Test Circuit Figure 2. ICCD Test Circuit Figure 3. AC Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz; tW = 500ns Input RL CL VCC Output Input = AC Waveform; tr = tf = 1.8ns; PRR = 10 MHz; Duty Cycle = 50% Input VCC A VOH GND Input Output tW tPLH tr = 3ns tf = 3ns tPHL VOL 50% 50% 50% 50% 90% 90% 10% 10% VCC 09-0002 |
