555 timer spice model
The 555 timer is commonly used as an astable multivibrator, a monostable multivibrator or a voltage-controlled oscillator. It consists of two comparators, a resistive voltage divider, a flip-flop and a discharge transistor. It is a two-state device whose output voltage level can be either high or low.
The output of the zero-cross detection is directly sent to the trigger input of the 555 timer. The control voltage is driven to teh input 5 of the 555 timer. The rheostat R9 is used to control the maximum delay of the 555 timer, so that with maximum control voltage, it will NOT exceed the length of a semi-period,...

A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electrons and holes as charge carriers. Unipolar transistors, such as field-effect transistors, use only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current ... The 556 is a dual version of the 555 timer housed in a 14-pin package, the two timers (A and B) share the same power supply pins. The circuit diagrams on this website show a 555, but they could all be adapted to use one half of a 556. The 556 is less popular and may cost more than two 555s so you may prefer to use two 555 timers.
