These Schottky-clamped circuits are designed to be used.
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 DM74LS decodes one-of-eight lines, based upon the conditions at the three binary select inputs and the three enable inputs. Two active-low and one active-high enable inputs reduce the need for external gates or invert- ers when expanding. A line decoder can be imple- mented with no external inverters, and a line decoder requires only one inverter. An enable input can be used as a data input for demultiplexing applications.
