What is a gated SR latch—also known as a clocked SR flip-flop—and how do they work? In this article, we learn how they work and their differences from a normal SR latch. Here is a short recap on what an SR latch is. It is a type of sequential logic with at least two inputs … Read more
A transistor SR latch (also called a two-transistor SR latch) is a basic bistable memory circuit built using only transistors instead of logic gate ICs. It stores one bit of information and shows how positive feedback creates stable logic states in sequential circuits. Not long ago, we discussed making an SR latch using logic gates … Read more
The SR latch (Set-Reset latch) is a simple digital circuit that stores one bit of information. It has two inputs—Set and Reset—that force the output on or off. When neither input is active, the circuit remembers its last state. In this article, we’ll examine how this behavior is implemented in real circuits, step by step. … Read more
TTL vs CMOS digital logic ICs differ significantly in their input and output characteristics, including voltage levels, current capability, and loading behavior. In this article, we’ll explore and compare their electrical characteristics, including input voltage, input current, and output behavior. Last time, we talked about different types of digital logic gates. Now, let’s look at … Read more
You may have heard of logic gates, but what exactly are they? Today, we will explore the basics of logic gates and their truth tables. Read more
