Abstract
A transistor circuit with hysteresis operation, which is formed with a detector part and selector part. The detector part detects a change in the level of an input signal according to one of first and second threshold levels, and generates an output signal having a level corresponding to the input signal. The level of the input signal is changed between a first level and a second level which is lower than the first level. The first and second threshold levels fall within a range defined between the first and second levels. The selector part selects one of the first and second threshold levels in accordance with the level of the output signal, and applies the selected one threshold level to the detector part.
