... Quad 2-Input Data Selectors/Multiplexer High-Performance Silicon-Gate CMOS The IN74HCT157A is identical in pinout to the LS/ALS157. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device routes 2 nibbles ( single port (Y) as determined by the Select input. The data is presented at the outputs in noninvertered form ...
