MC74HCT157A Multiplexer

MC74HCT157A Multiplexer Series Datasheet

The Motorola MC74HCT157A is identical in pinout to the LS157. 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 (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in noninverted form. A high level on the Output Enable input sets all four Y outputs to a low level.
