description/ordering information
The ’HC138 devices are designed to be used in
high-performance memory-decoding or data-
routing
applications
requiring
very
short
propagation delay times. In high-performance
memory systems, these decoders can be used to
minimize the effects of system decoding. When
employed with high-speed memories utilizing a
fast enable circuit, the delay times of these
decoders and the enable time of the memory are
usually less than the typical access time of the
memory. This means that the effective system
delay introduced by the decoders is negligible.
