DM54LS139 Product details

Description

These Schottky-clamped circuits 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 used with high-speed memories the delay times of these decoders are usually less than the typical access time of the memory This means that the effective system delay introduced by the decoder is negligible The LS138 decodes
