Product Summary
The SN74LVC138APWLE is a 3-LINE to 8-LINE decoders/demultiplexer. The SN74LVC138ADBR is designed for high-performance memory-decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, the SN74LVC138ADBR minimizes the effects of system decoding. When employed with high-speed memories utilizing 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.
