CD4047BF3A - Brand New Texas Instruments IC Chips
-
General Description
The 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.
Features
■ Wide supply voltage range: 3.0V to 15V
■ High noise immunity: 0.45 VDD (typ.)
■ Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LSSpecial Features
■ Low power consumption: special CMOS oscillator configuration
■ Monostable (one-shot) or astable (free-running) operation
■ True and complemented buffered outputs
■ Only one external R and C requiredMonostable Multivibrator Features
■ Positive- or negative-edge trigger
■ Output pulse width independent of trigger pulse duration
■ Retriggerable option for pulse width expansion
■ Long pulse widths possible using small RC components by means of external counter provision
■ Fast recovery time essentially independent of pulse width
■ Pulse-width accuracy maintained at duty cycles approaching 100%Astable Multivibrator Features
■ Free-running or gatable operating modes
■ 50% duty cycle
■ Oscillator output available
■ Good astable frequency stability
