Short for
Inter-IC, a type of
bus designed by Philips Semiconductors in the early 1980s, which is used to connect
integrated circuits (ICs). I2C is a
multi-master bus, which means that multiple
chips can be connected to the same bus and each one can act as a
master by initiating a data transfer. I2C is used in many devices, especially video devices such as
computer monitors, televisions and VCRs.
