  4-Line to 16-Line Decoders Demultiplexers
  General Description                                                  Features
  Each or these 4-line-to-16-line decoders utilizes TTL circuit-       Y   Decodes 4 binary-coded inputs into one of 16 mutually
  ry to decode four binary-coded inputs into one of sixteen                exclusive outputs
  mutually exclusive outputs when both the strobe inputs G1            Y   Performs the demultiplexing function by distributing data
  and G2 are low The demultiplexing function is performed                  from one input line to any one of 16 outputs
  by using the 4 input lines to address the output line passing        Y   Input clamping diodes simplify system design
  data from one of the strobe inputs with the other strobe             Y   High fan-out low-impedance totem-pole outputs
  input low When either strobe input is high all outputs are           Y   Typical propagation delay
  high These demultiplexers are ideally suited for implement-                 3 levels of logic 19 ns
  ing high-performance memory decoders All inputs are buff-                   Strobe 18 ns
