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 PS8622 07/23/02 PI74STX2G125 SOTiny™ Gate STX Dual Buffer with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 AC Loading and Waveforms VIN OPEN GND VCC OE Input RU Input tr = 3ns 90% Input 10% RD VCC 90% 50% Output CL tf = 3ns 50% 10% tW tPLH GND tPHL VOH Output 50% 50% CL includes load and stray capacitance Input PRR = 1.0 MHz; tW = 500ns VOL tf = 3ns Figure 1.
