ABSTRACT:
A data latch contains a supply connection, a reference ground potential connection and a data input. The input side of an inverter is connected to the data input, and it is coupled via a first switching device to the supply connection, and via a second switching device to the reference ground potential connection. Furthermore, a first multivibrator circuit having transistors of a first conductance type is provided, and is coupled to the supply connection. A second multivibrator circuit having transistors of a second conductance type is coupled to the reference ground potential connection. The transistors in the first and second multivibrator circuits in the data latch are connected to one another on the output side at a first node and at a second node, with the first node being connected to one output of the inverter, and the second node forming an output tap.
