description/ordering information

The ’HC139 devices are designed for
high-performance memory-decoding or
data-routing applications requiring very short
propagation delay times. In high-performance
memory systems, these decoders can minimize
the effects of system decoding. When employed
with high-speed memories utilizing a fast enable
circuit, the delay time 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.
