555 and 556 Timer Circuits

Introduction

The 8-pin 555 timer must be one of the most useful ICs ever made and it is used in many projects. With just a few external components it can be used to build many circuits, not all of them involve timing!
A popular version is the NE555 and this is suitable in most cases where a '555 timer' is specified. The 556 is a dual version of the 555 housed in a 14-pin package, the two timers (A and B) share the same power supply pins. The circuit diagrams on this page show a 555, ....etc

linear integrated circuits by d choudhury roy pdf free

A linear integrated circuit (linear IC) is a solid-state analog device characterized by a theoretically infinite number of possible operating states. It operates over a continuous range of input levels. In contrast, a digital IC has a finite number of discrete input and output states.

Within a certain input range, the amplification curve of a linear IC is a straight line; the input and output voltages are directly proportional. The best known, and most common, linear IC is the operational ....etc

Dynamic Logic Circuits

abstract

Dynamic logic is temporary (transient) in that output levels will remain valid only for a certain period of time
Static logic retains its output level as long as power is applied
Dynamic logic is normally done with charging and selectively discharging capacitance (i.e. capacitive circuit nodes)
Precharge clock to charge the capacitance
Evaluate clock to discharge the capacitance depending on condition of logic inputs
Advantages over static logic:
Avoids duplicating logic twi ....etc

The voltage and current at specified points in the circuits of analog chips vary continuously in time. In contrast, digital chips only use and create voltages or currents at discrete levels, with no intermediate values. In addition to Transistors, analog chips often have a larger number of passive elements (Inductor/Capacitors/Resistors) than digital chips typically do. Inductors tend to be avoided because of their large size, and a transistor and capacitor together can do the work of an inductor. (When this method is used in a CFL, you get an ....etc

What is electronics?

The word electronics is derived from electron mechanics, which means to study the behavior of an electron under different conditions of applied electric field.

The branch of engineering in which the flow and control of electrons in vacuum or semiconductor are studied is called electronics. Electronics can also be defined as the branch of engineering in which the electronic devices and their utilization are studied.

The motion of electrons through a conductor gives us electric current. This electric current can be ....etc
