description/ordering information
The ’AHC138 decoders/demultiplexers are designed for high-performance memory-decoding and data-routing
applications that require 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 usually are
less than the typical access time of the memory. This means that the effective system delay introduced by the
decoders is negligible.
