What is pin configuration of IC?

What is pin configuration of IC?

By convention, the pins on an IC are numbered counterclockwise, starting with the upper-left pin closest to the clocking mark. So, for example, with the clocking notch orienting the chip at the 12 o’clock position, the pins of a 14-pin IC are numbered 1 through 7 down the left side and 8 through 14 up the right side.

What is the function of pin number 5 of the IC 555?

Pin 5 of 555 Timer is the control pin. This makes the oscillator cycle more consistent. This pin can also be used to change the internal voltage reference to allow modifying the oscillator frequency or duty cycle.

How many pins an IC can have?

ICs are available in different packages. The photo below shows from left to right – an IC that contains logic gates packaged in a 14 pin package, a timer IC in an 8 pin package and a voltage regulator IC in a 3 pin package. Transistors are also available in the 3 pin package shown above.

What is the function of pin number 2 of IC 555 timer circuit?

Pin 2. It is the Trigger pin to activate the IC’s timing cycle. It is generally low signal pin and the timer is triggered when voltage on this pin is below one third of the supply voltage. The trigger pin is connected to the Inverting input of the comparator inside the IC and accepts negative signals.

What is the function of IC 555 pin No 8?

Pin diagram and description

Pin Name Purpose
7 DIS Open collector output which may discharge a capacitor between intervals. In phase with output.
8 Vcc Positive supply voltage, which is usually between 3 and 15 V depending on the variation.

What is 8 pin IC?

8 Pin IC Socket base adaptor is an 8 pin IC holder, which can be soldered directly onto the PCB. The IC can be removed from this socket when required. The IC is placed on the socket at the time of use. This base acts as a removable IC holder.

What are the inputs and outputs of 555 timer IC?

Pin3 is an output pin of 555 timer IC. The reset pin is used to reset or disable the timer irrespective of the trigger input. In normal operation, it is connected to high voltage. When supplied with a low signal, it will reset the output. Pin 5 is a control input pin. As the name indicates, it is used to control trigger and threshold inputs.

What is the pinout configuration of ic555?

Pinout configuration of IC555 Pin-1, GROUND: It is the GROUND PIN of the IC. The negative lead of DC power source or battery is attached to this pin. At this point observe that IC555 functions constantly on solitary rail power supply and In no way on dual power supply, in contrast to operational amplifiers.

How many resistors are in a 555 circuit?

The unit includes a pair of comparators a couple of transistors, a flip-flop and buffered output stage. The reference voltages for the a pair of comparators within the 555 are developed around a voltage divider comprising 3 equal resistors of 5K ohms each.

What are the applications of 5555 IC?

555 Timer IC is one of the commonly used IC among students and hobbyists. There are a lot of applications of this IC, mostly used as vibrators like, ASTABLE MULTIVIBRATOR, MONOSTABLE MULTIVIBRATOR, and BISTABLE MULTIVIBRATOR. You can find here some circuits based on 5555 IC.
