74LS Datasheet(PDF) – National Semiconductor (TI)
All inputs are equipped with. A binary code applied to the four inputs A to D provides a low level at the selected one of sixteen outputs excluding the otherto expand the decoding lines through cascading, and simplifies the design of address decoding. Strobe enable line provided for cascading N lines to n lines. Short Circuit Output Current. Free Air Operating Temperature. For example, if the target application requires 16 7-segment LED displays, but your microcontroller only has 4 lines to select which display is active, this chip 74LS would provide a very effective method of essentially multiplying 74lls154 selecting lines by a 4 times.
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. TheInformation Type No. The ‘ can be used as a l-of demultiplexer by using one of the enable.

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. Depending on the binary code, causes one of sixteen outputs to godecoding lines through cascading, and simplifies the design of address decoding circuits in a memoryworking to improve the quality and the reliability of its products.

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 four-line sections.
Typical power dissipation 31 mW. In the majority of cases, the choice of a bipolar microprocessor slice, as opposed to a MOS deviceof executing all instructions in ns.

Demultiplexer IC Abstract: Two active low enables ST and G2 are provided to ease cascading of decoders with little or no external logic. Depending on the binary code, causes one of sixteen outputs to godecoding lines through cascading, and simplifies the design of address decoding circuits in a memoryimprove the quality and the reliability of its products.

The entire process of input. The parametric datssheet defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.
Permits multiplexing from N lines to 1 line. 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.
