IC74163 Pin Diagram, Truth Table & Counter Circuit

IC74163 Integrated Presettable Synchronous 4-bit Modulo-16 Up counter. The IC is a synchronous counter as all 4 flip-flops are integrated into the same chip & they receive the same clock pulse (clock signal). The IC74163 is a completely programmable binary counter due to its four preset inputs, which allow it to begin counting with any […]

Short Circuit Protection Using Relay For Batteries

In this tutorial, we will see how to make a short circuit protection using Relay. Many times accidentally terminals of batteries and other power supplies get short-circuited. Due to this, they get hot and start degrading. In the case of lithium-ion or lithium-polymer batteries, they may catch fire due to short-circuit or even get blast. […]
