CD4047BM - Low Power Monostable/Astable Multivibrator

General Description

CD4047B is capable of operating in either the monostable or astable mode It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode and the output frequency in the astable mode Astable operation

Key Features

  • Positive- or negative-edge trigger Y Output pulse width independent of trigger pulse duration Y Retriggerable option for pulse width expansion Y Long pulse widths possible using small RC components by means of external counter provision Y Fast recovery time essentially independent of pulse width Y Pulse-width accuracy maintained at duty cycles approaching 100% Y Features Y Y Y.

CD4047BM CD4047BC Low Power Monostable Astable Multivibrator October 1993 CD4047BM CD4047BC Low Power Monostable Astable Multivibrator General Description CD4047B is capable of operating in either the monostable or astable mode It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode and the output frequency in the astable mode Astable operation is enabled by a high level on the astable input or low level on the astable input The output frequency (at 50% duty cycle) at Q and Q outputs is determined by the timing components A frequency twice that of Q is available at the Oscillator Output a 50% duty cycle is not guaranteed Monostable operation is obtained when the device is triggered
