The MK74ZD133 offers a unique power supply structure that effectively creates five separate blocks of

outputs. The main supply (VDD) goes to all internal circuitry and to 18 outputs, as shown in the Pin

Descriptions table. The other 14 outputs are split into 4 blocks that are powered independently of the main

VDD supply. Each block has its own supply which can be the same as VDD, less than VDD, or left

unpowered to shut off the corresponding outputs. For example, with VDD = 3.3 V, VDD5:8 can be

unconnected and the OUT5:8 levels will be floating. The table below summarizes the power supply control

of the MK74ZD133.
