Hot-selling and scarce SN74HC138D 3-Line To 8-Line Decoders/Demultiplexers SOP16 spot stock

Product Descriptions

The SNx4HC138 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 using 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.
