SN54LVC138A - 3-Line To 8-Line Decoder/Demultiplexer

The SN74LVC138A 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 minimize the effects of system decoding. When employed with high-speed memories using a fast enable circuit, delay times 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.
