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 PS8521F 05/10/05 PI74ST1G125 SOTiny™ Gate ST Buffer with 3-State Output AC Loading and Waveforms VIN OPEN GND VCC OE Input RU Input 90% Input Output 50% 10% tW VOl tf = 3ns tr = 3ns Figure 1.
