DM7446A, DM7447A

BCD to 7-Segment Decoders/Drivers

General Description

Features

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 circuit types feature lamp intensity modulation capa-

bility

■ Open-collector outputs drive indicators directly

■ Lamp-test provision

■ Leading/trailing zero suppression

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.
