DM7447A datasheet

Description :

The 46A and 47A, DM7447A feature active-low outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blanking input/output controls and a lamp test input. Segment identification and resultant displays are shown on a following page. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions.



– All circuit types feature lamp intensity modulation capability
– Open-collector outputs drive indicators directly
– Lamp-test provision
– Leading/trailing zero suppression
