3 Description
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...
