what would happen if u input a signal into an output pin of a chip?
Potential Risks of Using Output Pins as Input on Chips
In summary, connecting a signal to an output pin of a chip can have varying effects depending on the strength and source impedance of the signal, as well as the output driver and protective components on the chip. This could range from no harm to potentially damaging the output driver or other components on the chip.

Depends. If the output on the chip is strong, and the source impedance of your signal that you're connecting to the output is high (weak source), then it probably won't hurt the output of the chip. But if the source impedance of your signal is low (like a few ohms), and the driver for the chip output is not very beefy, then you will likely blow the output driver on the chip. Maybe even let a little smoke out of the chip...david90 said:

the chip could also have output capacitors onboard, or likely, protection diodes across or in series with the output built onto the chip. In this case, the voltage and power rating of the cap, and the current rating of the diodes will determine if they get damaged.
What is digital output?
Digital output is a type of signal that is used to transfer information between devices. It is a binary signal, meaning it can only have two states: on or off, high or low, or 1 or 0. It is commonly used in computers, electronics, and communication systems.
What is digital input?
Digital input is a type of signal that is received by a device. It is also a binary signal, with two possible states: on or off, high or low, or 1 or 0. Digital input is used to control the behavior of a device or to transfer data from one device to another.
How do digital output and input work together?
Digital output and input work together by using a common language of binary signals. The output device sends a binary signal to the input device, which interprets the signal and responds accordingly. This allows for the transfer of information and control of devices between different systems.
What are some examples of digital output and input devices?
Some examples of digital output devices include LED displays, speakers, printers, and servo motors. Digital input devices include keyboards, mice, sensors, and switches. These devices use binary signals to communicate with each other and with other systems.
What are the advantages of using digital output and input?
Digital output and input offer several advantages over analog signals, including better accuracy, reliability, and noise immunity. They also allow for faster data transfer and easier integration between different devices and systems. Additionally, digital signals are easier to process and manipulate, making them more versatile for various applications.
