KK74ACT151 Overview
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.
