Abstract
To provide a filter circuit and a semiconductor device capable of preventing circuit malfunction even when power supply voltage fluctuates. A filter circuit includes: a latch circuit configured to latch a set signal input to a first input terminal and a reset signal input to a second input terminal, respectively; and a rise adjustment unit configured to make a rise time of the set signal or the reset signal at power-on shorter than a time specified by a time constant circuit arranged in a preceding stage of the latch circuit.
