The HEF4047B is an integrated circuit containing a gatable astable multivibrator that is incorporated with logic techniques to allow positive or negative edge-triggered monostable multivibrator action ...

Many designs exist for logic-based astable multivibrators, one of the simplest being an RC feedback loop around a single inverting Schmitt trigger inverter (Figure 1). The output charges the capacitor ...

Fig 1. The voltage downconverter for high-power-density lithium-polymer batteries enables them to replace older battery technologies in applications that otherwise could not employ their higher ...
