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-blank-
ing input/output controls and a lamp test input. Segment
identification and resultant displays are shown on a follow-
ing 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 trail-
ing-edge, zero-blanking control (RBI and RBO). Lamp test
(LT) of these devices may be performed at any time when
the BI/RBO node is at a HIGH logic level. All types contain
an overriding blanking input (BI) which can be used to con-
trol the lamp intensity (by pulsing) or to inhibit the outputs.
Features
s All circuit types feature lamp intensity modulation

Note 6: The Absolute Maximum Ratingsare those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The Recommended Operating Conditionstable will define the conditions
for actual device operation.
