An output signal format defined as a rectangular wave capable of driving a multiple of CMOS loads. It has a positive signal peak greater than 90% of the supply voltage and a negative signal peak less than 10% of the supply voltage. The number of loads must be specified. Note that the "H" in HCMOS stands for high speed and does not affect the output voltage specification (MIL-PRF-55310D, 3.6.20).
