HEF4047B-[559]
Monostable/astable multivibrator
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). Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features and benefits
Monostable (one-shot) or astable (free-running) operation
True and complemented 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 components with external counter provision
Fast recovery time 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
