4-line To 16-line Decoders/demultiplexers - National Semiconductor

Each of these 4-line-to-16-line decoders DM54LS154 DM74LS154 utilizes TTL circuit- ry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs, G1 and G2, are low. The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low. When either strobe input is high, all outputs are high. These demultiplexers are ideally suited for implement- ing high-performance memory decoders. All inputs are buff- ered and input clamping Diodes are provided to minimize transmission-line effects and thereby simplify system de- sign. By National Semiconductor Corporation
