The diagrams in Figures 3 and 4 show the current flow in the MAX6951 during the multiplex cycles for digit and digit 1 respectively. The circuit shows the MAX6951's 8 internal power NMOS devices used for cathode drives CC0 through CC7, and the 9 segment drive current sources. The external LED digit connections for digits 2 through 7 are omitted for simplicity. Figure 3. The MAX6951 current flows d
