KEEPER

KEEPER Symbol

KEEPER is a weak keeper element used to retain the value of the net connected to its bidirectional O pin. For example, if a logic 1 is being driven onto the net, KEEPER drives a weak/resistive 1 onto the net. If the net driver is then tri-stated, KEEPER continues to drive a week/resistive 1 onto the net.

For additional information on using a KEEPER element with SelectI/O components, refer to the “SelectI/O Usage Rules” in the "IBUF_selectIO" section.
