74LS93 Decade Counter; 4-Bit Binary Counter

Description

74LS93 is an up counter built using four JK flip flops. It has a CP1 and Q0 that forms a mod 2 counter using a single flip flop. Also has CP0 with Q1, Q2 and Q3 with three flip flops which forms the mod 8 counter. It consists of a mode 2 up counter and a mod 8 up counter. Additionally, it is combined as mod 8 counter or divided by 2 or divide by 8 applications. Also built using four JK Flip Flops.
