MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Input Priority Encoder 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.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Input Priority Encoder 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.

The same limit applies for all D type input pins. To test input currents for other D inputs, individually apply proper voltage to pin under test. 2. Output latched to low state prior to test. 3. Output latched to high state prior to test. * To preserve reliable performance, the MC10165P (plastic packaged device only) is to be operated in ambient temperatures above 70°C only when 500 lfpm blown air or equivalent heat sinking is provided.
