DM74LS154

  Each of these 4-line-to-16-line DM74LS154 decoders 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 DM74LS154 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
