Abstract: A drive assist circuit includes a pulse generation circuit which outputs a pulse to control an assist operation when an assist signal makes a first transition corresponding to a transition of a gate signal from a high level to a low level. The pulse generation circuit includes a delay circuit provided in one of two inputs of a logic gate. The delay circuit is configured such that a delay is greater when an input makes a transition corresponding to the first transition of the assist signal, as compared to a case where the input makes a transition corresponding to an inverse of the first transition.

Abstract: An output circuit includes: a first p-type transistor having a source connected to VDDH and a gate to which an input signal is fed; and a second p-type transistor having a source connected to the drain of the first p-type transistor, a drain connected to an output terminal, and a gate connected to a first node. A capacitor has one terminal to which the input signal is fed and the other terminal connected to the first node. A first n-type transistor has a source connected to VDDL, a drain connected to the first node, and a gate to which a signal corresponding to the input signal is fed. A second n-type transistor has a source and a gate both connected to VDDL and a drain connected to the first node.
