BCD to 7-Segment Decoder/Driver with

Open-Collector Outputs

General Description

Features

■ Open-collector outputs

The DM74LS47 accepts four lines of BCD (8421) input

data, generates their complements internally and decodes

the data with seven AND/OR gates having open-collector

outputs to drive indicator segments directly. Each segment

output is guaranteed to sink 24 mA in the ON (LOW) state

and withstand 15V in the OFF (HIGH) state with a maxi-

mum leakage current of 250 µA. Auxiliary inputs provided

blanking, lamp test and cascadable zero-suppression func-

tions.

■ Drive indicator segments directly

■ Cascadable zero-suppression capability

■ Lamp test input
