DM7446A, DM7447A BCD to 7-Segment Decoders/Drivers
General Description
The DM7446A and 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 of the circuits incorporate automatic leading and/or trailing-edge, zero-blanking control (RBI and RBO).
Lamp test (LT) of these devices may ...
