MC10H165
APPLICATION INFORMATION
A typical application of the MC10H165 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.
