HEF4047B
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).
Key Features
- 1 General
- Monostable (one-shot) or astable (free-running) operation
- True and complemented buffered outputs
- Only one external resistor and capacitor required
- 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 recovery time independent of pulse width
