PRODUCT DESCRIPTION

LED

NE555 TIMER IC

IC CD4017

The importance Pins look at table below

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.
