DM74LS47

BCD to 7-Segment Decoder/Driver with Open-Collector

Outputs

General Description

Features

n Open-collector outputs

n Drive indicator segments directly

n Cascadable zero-suppression capability

n Lamp test input

The ’LS47 accepts four lines of BCD (8421) input data, gen-

erates 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 with-

stand 15V in the OFF (HIGH) state with a maximum leakage

current of 250 µA. Auxiliary inputs provided blanking, lamp

test and cascadable zero-suppression functions.
