简述:
Monostable/astable multivibrator
-
描述:
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.
