TECHNICAL DATA
8-Input Data Selector/Multiplexer
High-Speed Silicon-Gate CMOS
The KK74ACT151 is identical in pinout to the LS/ALS151,
HC/HCT151. The KK74ACT151 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The device selects one of the eight binary Data Inputs, as determined
by the Address Inputs. The Strobe pin must be at a low level for the
selected data to appear at the outputs. If Strobe is high, the Y output is
forced to a low level and the Y output is forced to a high level.
