What is 555 timer pin configuration?
555 Timer IC Pin Configuration. The 555 Timer IC is available as an 8-pin metal can, an 8-pin mini DIP (dual-in-package) or a 14-pin DIP. The pin configuration is shown in the figures. This IC consists of 23 transistors, 2 diodes and 16 resistors.
What is the function of pin number 5 of the IC 555?
Control: Pin 5 is the control pin. In most 555 circuits, this pin is simply connected to ground, usually through a small 0.01 μF capacitor. (The purpose of the capacitor is to level out any fluctuations in the supply voltage that might affect the operation of the timer.)
What Is pin number 2 IC 555?
trigger signal
IC-555 is a timer circuit. It produces accurate and highly stable time delays or oscillation. So Pin number-2 is used for the trigger signal. ∴ option (4) is correct.
What does pin 7 of 555 IC mean?
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 the fifth pin on a 555 timer IC?
Pin diagram and description
| Pin | Name |
|---|---|
| 3 | OUT |
| 4 | RESET |
| 5 | CTRL |
| 6 | THR |
What does pin 1 do on a 555 timer?
The 555 timer IC consist of 8-pins where each pin has some function. The pin configuration of this IC is shown below. Pin-1 is a GND pin which is used to supply a zero voltage to the IC.
What is IC pin number?
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.
