CD4047 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4047 has Monostable/Astable Multivibrator
CD4047 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
CD4047 Features
MONOSTABLE 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
ASTABLE MULTIVIBRATOR FEATURES
- Free-running or gatable operating modes
- 50% duty cycle
- Oscillator output available
- Good astable frequency stability
