HEF4047B

Monostable/astable multivibrator

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 recovery time independent of pulse width

 Pulse-width accuracy maintained at duty cycles

approaching 100%

2.3 Astable multivibrator

 Free-running or gatable operating modes

 50% duty cycle

 Oscillator output available
