Note 7: AC Parameters are guaranteed by DC correlated testing.
Typical Applications
Typical Connection Utilizing
the Ripple-Blanking Feature
First three stages will blank leading zeros, the fourth stage will not blank zeros.
Blanking Input Connection Diagram
When RBO/BI is forced LOW, all segment outputs are off regardless of the state of any other input condition.
