MC10H165
8–INPUT 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.
