POWER SOURCE INTERFACE, RECEIVING CIRCUIT, INTEGRATED CIRCUIT, AND SIGNAL TRANSMITTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a power source interface capable of generating an output signal while maintaining a relative relationship between a rise and a fall of an input signal even between different power sources.

SOLUTION: A power source interface includes: a transmitting circuit 11; and a receiving circuit 12. The receiving circuit 12 has: a first detecting section 18 which detects the transition of a first signal from a first signal level to a second signal level, and outputs a first detecting signal; a second detecting section 19 which detects the transition of a second signal from the first signal level to the second signal level within the same detection time as a detection time required for the first detecting section 18 to detect the transition of the first signal from the first signal level to the second signal level, and outputs a second detecting signal; and an output signal generating circuit 20 which generates an output signal OUT based on the first detecting signal outputted from the first detecting section 18 and the second detecting signal outputted from the second detecting section 19.
