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). 09-0007 3 PS8521I 12/02/09 PI74ST1G125 SOTiny™ Gate ST Buffer with 3-State Output AC Loading and Waveforms VIN OPEN GND VCC OE Input RU 90 I Input Output 90 50 50 10 10 RD CL P P 50 50 CL includes load and stray capacitance Input PRR = 1.0 MHz; tW = 500ns Figure 1.
