SEMICONDUCTOR TECHNICAL DATA  
The MC10165 is a device designed to encode eight inputs to a binary  
coded output. The output code is that of the highest order input. Any input  
of lower priority is ignored. Each output incorporates a latch allowing  
synchronous operation. When the clock is low the outputs follow the  
inputs and latch when the clock goes high. This device is very useful for  
a variety of applications in checking system status in control processors,  
peripheral controllers, and testing systems.  
The input is active when high, (e.g., the three binary outputs are low  
when input D0 is high). The Q3 output is high when any input is high. This  
allows direct extension into another priority encoder when more than  
eight inputs are necessary. The MC10165 can also be used to develop  
binary codes from random logic inputs, for addressing ROMs, RAMs, or  
for multiplexing data.
