Features:
- Decodes 4 binary-coded inputs into 1 of 16 outputs
- Distributes data from 1 input line to any of 16 outputs
- Input clamping diodes simplify system design
- High fan-out, low-impedance, totem-pole outputs
Each of these 4-line-to-16-line decoders utilizes TTL circuitry 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 implementing high-performance memory decoders. All inputs are buffered, and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.
Typical propagation delay: 3 levels of logic 23 ns Strobe 19 ns. Typical power dissipation: 45 mW.
