HEF4047B Overview
The HEF4047B consists of a gatable astable multivibrator incorporating logic techniques to permit positive or negative edge-triggered monostable multivibrator action with retriggering and external counting options. Inputs include +TRIGGER, TRIGGER, ASTABLE, ASTABLE, RETRIGGER and MR (master reset). Buffered outputs are O, O and OSCILLATOR OUTPUT.
HEF4047B Key Features
- Monostable (one-shot) or astable (free-running) operation
- True and plemented buffered outputs
- Only one external resistor and capacitor required
- 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 ponents
- Fast recovery time independent of pulse width
- Pulse-width accuracy maintained at duty cycles
- Free-running or gatable operating modes
