PRODUCT DESCRIPTION
LED
NE555 TIMER IC
Pin |
Name |
Purpose |
1 |
GND |
Ground reference voltage, low level (0 V) |
2 |
TRIG |
The OUT pin goes high and a timing interval starts when this input falls below 1/2 of CTRL voltage (which is typically 1/3 Vcc, CTRL being 2/3 Vcc by default if CTRL is left open). In other words, OUT is high as long as the trigger low. Output of the timer totally depends upon the amplitude of the external trigger voltage applied to this pin. |
3 |
OUT |
This output is driven to approximately 1.7 V below +Vcc, or to GND. |
4 |
RESET |
A timing interval may be reset by driving this input to GND, but the timing does not begin again until RESET rises above approximately 0.7 volts. Overrides TRIG which overrides threshold. |
5 |
CTRL |
Provides “control” access to the internal voltage divider (by default, 2/3 Vcc). |
6 |
THR |
The timing (OUT high) interval ends when the voltage at threshold is greater than that at CTRL (2/3 Vcc if CTRL is open). |
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. |

1.) Pin 16 is positive power supply and pin 8 is a ground.
The power supply range of 3 volts to 16 volts and Maximum power supply voltage at pin 1 must not much than 18 volts.
2.) Pin 13 is Clock enabled pins to controls the clock. When it is “0” logic, the clock is enabled and the counter advances one count for each clock pulse.
When “1” logic, the clock input is stop, and the counter does nothing even when clock pulse arrive.
3.) Pin 14 is the clock triggers one count.
The clock pulse must be “clean”.
If they are “noisy” the counter may advance two or more times during each clock pulse.
4.) Pin 15 is the reset pin. Normally, it is “0”. When made “1”, the counter is reset to “0”.
5.) Pins 1-7 and 9-11 are the decoded output pins.
The active count pin goes high and all others remain low.
6.) Pin 12 is Carry output, for the clock input of an additional counter or an external circuit that the count is complete.
