mc10h165 http://onsemi.com 3 8input priority encoder the mc10h165 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 mc10h165 can also be used to develop binary codes from random logic inputs, for addressing roms, rams, or for multiplexing data. c 4 d0 5 d1 7 d2 13 d3 10 d4 11 d5 12 d6 9 d7 6 v cc1 = pin 1 v cc2 = pin 16 v ee = pin 8 . 3 q0 2 q1 15 q2 14 q3 logic diagram numbers at ends of terminals denote pin numbers for l and p packages.
mc10h165 http://onsemi.com 4 application information a typical application of the mc10h165 is the decoding of system status on a priority basis. a 64line 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. q2 six bit output word yielding number of highest priority channel present at input zzz mc10h164 mc10h164 mc10h164 x0 x7 . . . . . . . a b c c d0 d7 q0 q1 q2 lsb msb mc10h165 mc10h165 mc10h165 mc10h165 mc10h165 mc10h165 mc10h165 mc10h165 c d0 d7 q0 q1 q2 q3 c d0 d7 c d0 d7 c d0 d7 c d0 d7 c d0 d7 c d0 d7 c d0 d7 q0 q1 q2 q3 q0 q1 q2 q3 q0 q1 q2 q3 q0 q1 q2 q3 q0 q1 q2 q3 q0 q1 q2 q3 q0 q3 1/2 mc10h101 system clock highest priority input lowest priority input 64line priority encoder x0 x7 . . . . . . . a b c x0 x7 . . . . . . . a b c q1
