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 […]
Optoisolators and Optocoupler sound very similar and they are the same in terms of workings and other features lets see what are optoisolators and optocoupler. There are some differences due to which they are given different names. Photocoupler is another name of the optocoupler. An optocoupler or photocoupler and an optoisolator are semiconductor devices that […]
In this article, you will Know about three different types of the fan regulator circuit. The first one is resistor based, the second one is triac based and the third one is capacitor-based. You must have seen those conventional old and big resistive fan regulators. Those conventional regulators use resistive wires connected between load and […]
A Schmitt Trigger circuit is a comparator circuit with some modifications. As compared to a normal comparator circuit the Schmitt trigger circuit has a hysteresis curve. This means that it has two threshold voltages an upper threshold and a lower threshold voltage. In Schmitt trigger circuit hysteresis is created by applying positive feedback to the non-inverting […]
Gunn diode operates on the Gunn effect which is named after its inventor J.B. Gunn. He discovered the periodic variation of current in a GaAs (gallium arsenide) rod in 1963. The microwave device that operates on the principle of transfer of electrons is called as Gunn diode. This is one of the diodes used as […]
The VI characteristics of IGBT is as shown in Figure. In the forward direction, they are similar to those of bipolar transistors. The only difference here is that the controlling parameter is the gate to source voltage Vgs and the parameter being controlled is the drain current. The working principle of IGBT is based on […]
