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.
