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.

1. 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 70C only when 500 lfpm blown air or equivalent heat sinking is provided. Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained. Outputs are terminated through a 50-ohm resistor to -2.0 volts. Test procedures are shown for only one gate. The other gates are tested in the same manner.

APPLICATION INFORMATION
A typical application of the MC10165 is the decoding of system status on a priority basis. A 64 line priority encoder is shown in the figure below. System status lines are
connected to this encoder such that, when a given condition exists, the respective input will be at a logic high level. This scheme will select the one of 64 different system conditions, as represented at the encoder inputs, which has priority in determining the next system operation to be performed. The binary code showing the address of the highest priority input present will appear at the encoder outputs to control other system logic functions.
