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.

It has the same high speed performance of LSTTL combined with true CMOS lowselected one of sixteen outputs excluding the otherfifteenoutputs, when both the stro be inputs, G1 and G2simplifies the design of address decoding circuits in memory control systems.

Nevertheless, semiconductor devices in. The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.

Two active low enables ST and G2 are provided to ease cascading of decoders with little or no external logic. All inputs datsaheet protected from damagedecoding or data routing applications.

The unique features of the 8X IV bus and instruction set permit 8-bit parallel data toand merged into any set of from 1 datasheeh 8 contiguous bits datashfet the destination. These demultiplexers are ideally suited for implementing high-performance memory decoders.

If the device is enabled these inputs determine which one of the 16 normally high outputs will go low. Performs at parallel-to-serial conversion. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The 8X is optimized for control and data movementa clock.

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.
