7 Segment ( Cathode) 634 The 54HC/74HC logic family is

The 54HC/74HC logic family is functionally as well as pin-out compatible with the standard 54LS/74LS logic family

Day or night detection

Presettakes place regardless of the levels at count enable inputs (CEP and CET)

Tie Wrap is used to bunch cables in a neat bunch

Works with both 3

7 Segment ( Cathode) 634 The 54HC/74HC logic family isIntroduction : 7 Segment common cathode display. All the cathodes of the LEDs in a 7 segment connected together and the common anode has all the anodes of the LEDs in a 7 segment connected together. In the common cathode display, all the cathode connections of the LED segments are connected together to 'logic 0' GND.
