DM74LS48

BCD to 7-Segment Decoder

General Description

The ’LS48 translates four lines of BCD (8421) input data

into the 7-segment numeral code and provides seven corre-

sponding outputs having pull-up resistors as opposed to

totem pole pull-ups These outputs can serve as logic sig-

nals with a HIGH output corresponding to a lighted lamp

segment or can provide a 13 mA base current to npn lamp

driver transistors Auxiliary inputs provide lamp test blank-

ing and cascadable zero-suppression functions

The ’LS48 decodes the input data in the pattern indicated in

the Truth Table and the segment identification illustration
