Description
The HEF4047B is a retriggerable astable multivibrator that can be configured as either a positive-edge or negative-edge triggered monostable multivibrator.
The output pulse width is programmed by selection of external components (Rt and Ct).
Inputs include clamp diodes.
Features
- 2.1 General.
- Monostable (one-shot) or astable (free-running) operation.
- True and complemented buffered outputs.
- Only one external resistor and capacitor required 2.2 Monostable multivibrator.
- Positive- or negative-edge triggering.
- Output pulse width independent of trigger pulse duration.
- Retriggerable option for pulse-width expansion.
- Long pulse width possible using small RC components with external counter provision.
- Fast.
