Features and benefits
General
- Monostable (one-shot) or astable (free-running) operation
- True and complemented buffered outputs
- Only one external resistor and capacitor required
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
- Pulse-width accuracy maintained at duty cycles approaching 100%
Astable multivibrator
- Free-running or gatable operating modes
- 50% duty cycle
- Oscillator output available
