7447A - BCD to 7-Segment Decoders/Drivers

Download the 7447A datasheet PDF. This datasheet also covers the 7446A variant, as both devices belong to the same bcd to 7-segment decoders/drivers family and are provided as variant models within a single manufacturer datasheet.

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.

DM7446A, DM7447A BCD to 7-Segment Decoders/Drivers September 1986 Revised July 2001 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 be performed at any time when the BI/RBO node is at a HIGH logic level.
