SEMICONDUCTOR TECHNICAL DATA  
N SUFFIX  
PLASTIC PACKAGE  
CASE 648–08  
16  
High–Performance Silicon–Gate CMOS  
1
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.  
D SUFFIX  
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.
