Product Summary

 3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS

informationThe ’HC138 devices are designed to be used inhigh-performance memory-decoding or data-routingapplicationsrequiringveryshortpropagation delay times. In high-performancememory systems, these decoders can be used tominimize the effects of system decoding. Whenemployed with high-speed memories utilizing afast enable circuit, the delay times of thesedecoders and the enable time of the memory areusually less than the typical access time of thememory. This means that the effective systemdelay introduced by the decoders is negligible
