DM74LS47
BCD to 7-Segment Decoder/Driver with
Open-Collector Outputs
General Description
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
μ
A. Auxiliary inputs provided
blanking, lamp test and cascadable zero-suppression func-
tions.
