3 Description
The SN74LVC138A devices are designed for highperformance
memory-decoding or data-routing
applications requiring very short propagation delay
times. In high-performance memory systems, these
decoders minimize the effects of system decoding.
When employed with high-speed memories using a
fast enable circuit, 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.
