FUNCTIONAL DESCRIPTION F158A quad 2-input multiplexer selects four bits data from sources under control common Select input presents data inverted form four outputs. Enable input active LOW. When HIGH, outputs forced HIGH regardless other inputs. F158A logic implementation 4-pole, 2-position switch where position switch determined logic levels supplied Select input. common F158A moving data from groups registers four common output busses. particular register from which data comes determined state Select input. less obvious function generator. F158A generate four functions variables with variable common. This useful implementing gating functions.
