r 9311/DM9311 4-Line to 16-Line Decoders/Demultiplexers General Description Features Each of these 4-line-to-16-line decoders utilizes TTL circuit- ™ Pin for pin with popular DM54154/74154 ry to decode four binary-coded inputs into one of sixteen ™ Decodes 4 binary-coded inputs into one of 16 mutually mutually exclusive outputs when both the strobe inputs, G1 exclusive outputs: and G2, are low. The demultiplexing function is performed —_m Performs the demultiplexing function by distributing data by using the 4 input lines to address the output line, passing from one input line to any one of 16 outputs data from one of the strobe inputs with the other strobe Input clamping diodes simplify system design input low. When either strobe input is high, all outputs are g High fan-out, low-impedance, totem-pole outputs high. These demultiplexers are ideally suited for implement- a * mati , it ‘i © Typical propagation delay 19 ns ing high-performance memory decoders.
