The ripple-blanking input (RBI) must be open or high if blanking of a decimal zero is not desired. — [3] When a low logic level is applied directly to the blanking input (BI), all segment outputs are off regardless of the level of any other input. — [4] When ripple-blanking input (RBI) and inputs A, B, C, D are at a low level with the lamp test input high, — all segment outputs go off and the ripple-blanking output (RBO) goes to a low level (response condition). — — [5] When the blanking input/ripple blanking output (BI/RBO) is open or held high and a low is applied to the lamp test input, all segment outputs are on.
