nputs High–Performance Silicon–Gate CMOS The 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. The HCT157A is similar in function to the HC257 which has 3–state outputs. • • • • • • Output Drive Capability: 10 LSTTL Loads TTL NMOS Compatible Input Levels Outputs Directly Interface to CMOS,
