Claim 0:
1. An integrated circuit, including:
an input pad; and
a Schmitt trigger including:
an input coupled to the input pad;
a first main transistor branch coupled between a high supply voltage and an intermediate node;
a charging assistance circuit including:
a parallel transistor branch of a first conductivity type coupled between the high supply voltage and the intermediate node;
pass transistor coupled between the input pad and the parallel transistor branch;
a switching storage element coupled to a gate terminal of the pass transistor; and
