摘要：
Disclosed is an input circuit (1') provided with a time-delay element (40), said circuit being able to be tested by a controlled high level or low level connection, and a method for the operation thereof, wherein the delay time of the time-delay element (40) can be modified during the operation of said input circuit (1'). According one embodiment, the expired delay time is read out prior to the test and re-produced after the test, whereby an increase in the active input delay time for the process signals resulting from the test is avoided and also or alternately whereby the delay time prior to the test is set to a minimum value to enable a quick test of the input circuit (1') to be carried out independently from the adjusted delay time.
