Logic Gate Circuit. The earliest ttl gate circuit was the 74 series and then the 74h series 74l series 74ls 74as 74als and other series appeared. Logic gates act as switches in a circuit that performs logical operation.
Here the inputs and output of all the gates of integrated devices can be accessible and also the external connections are made available to them just like discrete logic gates. The relationship between the input and the output is based on a certain logic. Logic gates may be strung together and combined almost infinitely and such combinations can be designed to make pretty complex decisions based on any number of variables.
It is an electronic circuit having one or more than one input and only one output.
Ttl is mainly composed of a bjt bipolar junction transistora and a resistor. Logic gates are used to carry out logical operations on single or multiple binary inputs and give one binary output. Iv cmos logic gate circuit 1. It can be designed using any non linear device.
