What is pin diagram of 555 timer?
Pin diagram and description
What is the function of the pin 5 in 555 timer?
Pin 5. – Control Voltage, This pin controls the timing of the 555 by overriding the 2/3Vcc level of the voltage divider network. By applying a voltage to this pin the width of the output signal can be varied independently of the RC timing network.
How many pins are there in 555 timer?
Pinout. The pinout of the 8-pin 555 timer and 14-pin 556 dual timer are shown in the following table.
What is IC 555 Principle?
Functions of 555 timer IC. The 555 timer power supply has high range from +5volts to +18 volts. The load current for the 555 timer is sourcing 200 mA. The 555 timer has high output current and the output is driven for the TTL. To change in temperature in the 555 timer it has a temperature stability of 50 ppm/ degree.
What is Vcc and GND in IC?
VCC (Voltage Common Collector) is the higher voltage with respect to GND (ground). VCC is the power input of a device. It may be positive or negative with respect to GND. When the only positive power supply is used then VSS (Voltage Source Supply) means ground or zero.
What is the application of 555 timer?
The standard 555 timer IC is used in a variety of timer, pulse generation and oscillator applications. It can be used to provide time delays, as oscillators and as flip-flop elements. The 555 timer IC is an integral part of electronics projects.
What are the features of 555 timer?
Features of the 555 Timer IC It can be operated in +5V, can withstand up to +18V. The source and sink current of the output pin is near about 200mA. Trigger Voltage is 1.6 when operating at +5V. Operating Temperature is near about 70 degrees Celsius.
What is the function of the pin 8 of IC 555?
Pin 8. It is positive rail connected pin which is connected to positive terminal of the power supply. It is also known as Vcc. IC555 works in a wide range of voltage from 5V to 18 V DC where as the CMOS version 7555 works with 3 Volts.
Is VCC DC or AC?
VCC of a bipolar junction transistor is the DC voltage that is supplied to the collector of the transistor. VCC is a very important voltage when biasing the transistor because it determines how much the AC signal can be amplified to in the transistor.
Is GND positive or negative?
Ground is an arbitrary reference point you can choose wherever you want. All other potentials in the circuit are measured relative to ground. So by definition, ground is at 0 potential and it is neither positive or negative.
What is IC pin?
The pins on an IC chip provide connections to the tiny integrated circuits inside of your electronics. To determine which pin is which, you look down on the top of the IC for the clocking mark, which is usually a small notch in the packaging but might instead be a little dimple or a white or colored stripe.
What is V and V+?
+V connects to the (+) Terminal of the 9 Volt Battery. -V connects to the (-) Terminal of the 9 Volt Battery. Technically, there is no “ground” in this circuit since it is a “floating” design.
