This paper deals with the class of all discrete time-varying bounded linear systems in a Banach space for which the state sequence remains in a bounded region whenever the input sequence is constrained to (another) bounded region. A necessary and sufficient condition for membership to such a class is given, as well as a full description of its subclasses obtained by fixing a priori those bounded regions.
