APPLICATION INFORMATION
General features:
Monostable multivibrator features:
Astable multivibrator features:
January 1995
Minimum MR pulse
Minimum input
Monostable (one-shot) or astable (free-running)
operation
True and complemented buffered outputs
Only one external R and C 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 components
by means of external counter provision
Fast recovery time essentially independent of pulse
width
Pulse-width accuracy maintained at duty cycles
approaching 100%
Free-running or gatable operating modes
50% duty cycle
Oscillator output available
Monostable/astable multivibrator
