Rs. 23.00 Rs. 18.00 (Exc. GST)

The CD4047 is a high voltage multivibrator IC, that can operate in both Monostable and Astable mode. The IC requires an external resistor and capacitor to set the width of output pulse in monostable mode and the frequency of output pulse in Astable Mode. The monostable mode has positive and negative edge trigger with programmable pulse width. The Astable mode provides good frequency stability at 50% duty cycle. The CD4047 IC can operate on 5V, 10V, 15V or even at 20V. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC is commonly used in frequency discriminators, timing circuits ,time-delay applications ,envelope detection, frequency multiplication and division.
