The name “transistor” is a portmanteau of the words Transistor vs Resistor. Transistors are one of the most significant inventions of the last century. Without further ado… What is a Transistor?

However, we thought it was time to give a detailed explanation of the differences between these transistors and resistors to clear up any confusion.īy the end of this guide, you should have a full understanding of these components’ functions, in addition to how you can use them in your next electronics project. We have a comprehensive list of all PCB components on our website. It is their functions that may confuse beginners. However, the issue does not just lie in how we have chosen to name them. This article was first published on 17 August 2017 and was updated on 28 September 2022.Mixing up terms or jargon is common in electronics, especially when talking about transistor vs resistor.

Truth Table: TĪlso Read: T Flip Flop Working Applications Toggle, hence they are named Toggle flip-flops. These flip-flops are called T flip-flops because of their ability to complement their state i.e. It has only one input along with the clock input. This modified form of the JK is obtained by connecting inputs J and K together. These are basically single-input versions of JK flip-flops. Recommended: D Flip Flop Working and Applications T Flip-FlopĪ T flip-flop is like a JK flip-flop. The output (Q) is the same as the input and can only change at the rising edge of the clock. The change of state of the output is dependent on the rising edge of the clock. In the D flip-flops, the output can only be changed at the clock edge, and if the input changes at other times, the output will be unaffected. They are commonly used for counters and shift registers and input synchronization. Truth Table: JĪlso Read: Everything you need to know about JK Flip Flop D Flip-Flopĭ flip-flop is a better alternative that is very popular with digital electronics. JK Flip-Flops can function as Set or Reset Flip-flops. If J and K are both high at the clock edge, then the output will toggle from one state to the other. If J and K are both low, then no change occurs. high and low), then the output Q takes the value of J at the next clock edge. In simple words, If J and K data input are different (i.e. However, the outputs are the same when one tests the circuit practically. The input condition of J=K=1 gives an output inverting the output state. The JK flip-flop is an improvement on the SR flip-flop where S=R=1 is not a problem. Recommended: SR Flip Flop Explained JK Flip-Flopĭue to the undefined state in the SR flip-flops, another flip-flop is required in electronics. The truth table of SR Flip-Flop is highlighted below. The two outputs, as shown above, are the inverse of each other. Once the outputs are established, the wiring of the circuit is maintained until “S” or “R” go high, or power is turned off.Īs shown above, it is the simplest and easiest to understand. In this system, when you Set “S” as active, the output “Q” would be high, and “Q ‘ ” would be low. This simple flip-flop circuit has a set input (S) and a reset input (R). This is the most common flip-flop among all.
There are basically 4 types of flip-flops: Let’s understand the flip-flop in detail with the truth table and circuits. Otherwise, even if the S or R is active, the data will not change. the stored data is changed) only when you give an active clock signal. In this circuit diagram, the output is changed (i.e.
(This is an active-low circuit so active here means low, but for an active high circuit, active would mean high) SR LatchĪ flip-flop, on the other hand, is a synchronous Circuit and is also known as a gated or clocked SR latch. In this circuit when you Set S as active, the output Q will be high and Q’ will be Low. įor example, let us talk about SR latch and SR flip-flops. If you are confused between latch and flip-flop, then you should check this detailed article where we discussed the difference between Latch and Flip Flop. Flip Flops are edge-triggered and a latch is level-triggered.
