operation.
These 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 used 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.
