ABSTRACT:
An input circuit has an inverter and a differential amplifier, which are respectively connected on an input side to an input and on an output side to an output of the input circuit. The input circuit has two operating modes defined by an activation signal, the differential amplifier being activated and the inverter being deactivated in a first operating mode, and the differential amplifier being deactivated and the inverter being activated in a second operating mode. In this manner, the input circuit has the advantage of selective operation with LVTTL or SSTL levels.
