Description: 7448 SN74HC48N 74HC48 74LS48 DIP 14 Pin IC
The ‘LS48 translates four lines of BCD (8421) input data into the 7-segment numeral code and provides seven corresponding outputs having pull-up resistors, as opposed to totem pole pull-ups. These outputs can serve as logic signals, with a HIGH output corresponding to a lighted lamp segment, or can provide a 1.3 mA base current to npn lamp driver transistors. Auxiliary inputs provide lamp test, blanking and cascad able zero-suppression functions. The ‘LS48 decodes the input data in the pattern indicated in the Truth Table and the segment identification illustration.
