Different Types of Digital Logic Gates

In the presence of different digital signals that need to be combined to make a logical decision, engineers use different types of digital logic gates. Usually, these gates have several inputs but a single digital output. Where a larger logic gate function or a sequential or combinational circuit is required, it is usual for individual logic gates to be connected together. Digital logic gates in standard commercial form are available in two basic forms or families – TTL or Transistor-Transistor Read more [...]

What is Transistor-Transistor-Logic – TTL?

TTL or Transistor-Transistor Logic is a type of digital circuit that is made from BJT or bipolar junction transistor along with resistors. Both the amplifying function and the logic gating function are carried out through transistors, thus the name transistor-transistor logic. TTL is used for many applications like industrial controls, computers consumer electronics, test equipment, synthesizers and more. The TTL designation is also used in some places to imply ‘compatible logic levels’ Read more [...]
