SEMICONDUCTOR TECHNICAL DATA  
The MC14514B and MC14515B are two output options of a 4 to 16 line  
decoder with latched inputs. The MC14514B (output active high option)  
presents a logical “1” at the selected output, whereas the MC14515B (output  
active low option) presents a logical “0” at the selected output. The latches  
are R–S type flip–flops which hold the last input data presented prior to the  
strobe transition from “1” to “0”. These high and low options of a 4–bit latch/4  
to 16 line decoder are constructed with N–channel and P–channel  
enhancement mode devices in a single monolithic structure. The latches are  
R–S type flip–flops and data is admitted upon a signal incident at the strobe  
input, decoded, and presented at the output.
