Step 1 of 2 3.24DP It is known that, the maximum output Voltage or maximum power consumption is happen when the input voltage is same as the output voltage. That is, Where, is the input voltage of the CMOS circuit is the output voltage of the CMOS circuit It is also known that, the maximum output voltage is equal to the half of the supply voltage. Where, is the maximum output Voltage Step 2 of 2 From the datasheet of CMOS device 74HC00, the value of the HIGH voltage is Now, calculate the input level of the 74HC00 to consume the most power. = 2.2 V Thus, the input level of the 74HC00 to consume the most power is 2.2 V -
