DM7446AJ 技术参数

June 1989

DM7446A, DM5447A/DM7447A

BCD to 7-Segment Decoders/Drivers

General Description

The 46A and 47A feature active-low outputs designed for

driving common-anode LEDs or incandescent indicators di-

rectly. All of the circuits have full ripple-blanking input/out-

put controls and a lamp test input. Segment identification

and resultant displays are shown on a following page. Dis-

play patterns for BCD input counts above nine are unique

symbols to authenticate input conditions.

an overriding blanking input (BI) which can be used to con-

trol the lamp intensity (by pulsing) or to inhibit the outputs.

Features

All circuit types feature lamp intensity modulation

capability

Open-collector outputs drive indicators directly

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

Lamp-test provision

Leading/trailing zero suppression
