Here we will discuss 74LS93 which is a 4 BIT COUNTER. It consists of 4 JK FLIP FLOP which act on the input pulse no matter how we gave the input pulse. We can use the microcontroller or timer IC for pulse input. The 74LS93 IC comes up with two reset pins, two clock pins, and four output pins. The IC is made up of two counters one is mod 2 counter another one is mod 8 counter. The whole IC gives the output 4 bits which counts from 0 to 15 in binary. This is compatible with any microcontroller or TTL based devices. It comes in multiple packages such as DIP, SMD with all 14-pins. The 74L93 binary counter comes up with internal protection from high-speed termination
