I'm a mechanical engineer starting with electronics.I am unable to understand concepts like pull\push, open collector, tristate etc.
Please help me with tips,links,books etc.

Active pull/push refers to the electrical signals used to control the flow of current in electronic circuits. It involves actively pulling or pushing the voltage levels to a certain state, either high or low, to turn on or off a device or component.
Open collector is a type of output circuit in which the collector of a transistor is not connected to any voltage supply. Instead, it is left open, allowing the output to be controlled by the pull-up resistor and external logic. This allows for multiple outputs to be connected together without interference.
Three-state logic is a type of logic circuit that allows for three possible outputs: high, low, and high impedance. The high impedance state allows the output to be disconnected from the circuit, reducing power consumption and preventing interference with other outputs.
The main difference between active and passive pull/push is that active pull/push involves actively controlling the voltage levels, while passive pull/push relies on the natural flow of current. Active pull/push is more commonly used in modern electronic circuits as it allows for faster and more precise control.
Active pull/push, open collector, and three-state logic are commonly used in digital circuits, such as microcontrollers, memory chips, and data buses. They are also used in communication systems, such as buses and networks, to control the flow of data and prevent interference.
