It was probably caught by reddit's spam filters. Although, 74LS93 is a 4 bit counter and it can counter from 0-16 in binary and we can use two seven-segment displays to show counter values. This decimal counter counts from zero to nine. ![]() A, B, C & D are the BCD inputs where A represents the LSB and D. In this example, we used two 74LS20 ( 4 input NAND gate) and 3 Not gates 74LS04 to design a decimal counter with BCD seven-segment display. Tech support help can be found in /r/gadgets. CA sP11.4 (5 pts) The 7447N IC is a BCD/7-segment Decoder with the Multisim pin-out diagram as shown. If you have specific, targeted questions regarding homework, we will help you out only if you have provided some beginning work. Power, electronics, electromagnetics, semiconductors, software engineering, embedded systems - all topics relevant to this field, professional or academic. The basic idea involves driving a common cathode 7-segment LED display using combinational logic circuit. ![]() Discuss anything related to the field of Electrical and Computer Engineering.
