74LS93 Decade & Binary Counter
The #74LS93 decade and #binary #counter IC contains two independent counters, similar to the #74LS90 IC. It can count from 0 to 15 according to the formula #7493 2 n -1 with 4 master slaves JK flip-flops.
74HC154 Demultiplexer
#74HC154 #decodes #binary encoded #BCD data and transfers it to the output. Convert 4 lines of data to 16 lines and works as demultiplexer. 74HC154 works with 5V and you can get maximum 16mA current from each channel.
74HC595 Shift Register
#74HC595 is a Serial In Parallel Out (SIPO) shift register integrated circuit. #SN74HC595N has a total of 16 legs and 8 of these legs are for outputs. The #74HC595N, which has a wide range of usage, is produced in #TTL structure and operates with 5V.
74LS90 Decade Binary Counter
#7490 #74ls90 contains two independent counters used in counter #circuits. It can perform #BCD counting or #Bi-Quinary counting with the connection of the clock signal and output ports
7447 BCD to 7 Segment Decoder
The #7447 ic is used to drive common anode 7 segment displays. You can directly connect the #7segment #displays to 7447, which has open collector outputs.
NE555 - Timer Oscillator
NE555 oscillator – 555 timer chip can achieve clock pulse, time delay circuit, or PWM (square wave) using only a few passive components.
