3-Way On/Off Switch: Control multiple devices with a single remote
Ne556 Dual Timer Ic ac relay Based on MCU Device USBThese devices provide two independent timing circuits of the NA555, NE555, SA555, or SE555 type in each package. These circuits can be operated in the astable or the monostable mode with external resistor capacitor (RC) timing control. The basic timing provided by the RC time constant can be controlled actively by modulating the bias of the control voltage input. Features: Two Precision Timing Circuits Per Package Astable or Monostable Operation TTL
