Abstract
An apparatus is disclosed for receiving input signals in a first higher voltage domain and for generating and outputting signals in a second lower voltage domain, said apparatus comprising: an input pad; output circuitry, said output circuitry being configured to switch to output a first predetermined value in response to a rising input signal exceeding an upper threshold value and to switch to output a second predetermined value in response to a falling input signal falling below a lower threshold value; a first input path; a second input path; and a controllable connecting path between said first and second inputs.
