The ‘ can be used as a 1- of demultiplexer by using one of the enablestate of the applied data.
4 Line to 16 Line Demultiplexer / Decoder
Each or these 4-line-toline 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.
Not more than one output should be shorted at a time, and the duration should not exceed one second.
The device should not be operated at these limits. Measured by terminal at no. Input Current Max Input Voltage.

Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller. Separate strobe inputs are provided for each of the two vatasheet sections. 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.
All typicals are at V. Life support devices or systems are devices or systems. Devices also available in Tape and Reel. Understand, this is a typical example of application, not it’s sole purpose. All inputs are protected from damage due to static dischargedata routing applications.
