The ‘ can be used as a l-of demultiplexer by using one of the enable. High fan-out, low impedance, totem pole outputs. LS circuit diagram of 74ls 1 to 16 demultiplexer decoder pin configuration of pin diagram decoder pin diagram of 74ls 74LS N74LSN Text: When either strobe input is high, all outputs are high. 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.
Life support devices or systems are devices or systems. No abstract text available Text: All inputs are equipped with. Advanced Electronic Packaging Abstract: Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller. 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 you selecting lines by a 4 times.
Understand, this is a typical example of application, not it’s sole purpose.
Alt inputs are equipped with. These demultiplexers are ideally suited for implementing high-performance memory decoders.

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 memoryworking to improve the quality and the reliability of its products.
Input Current Max Input Voltage. Performs at parallel-to-serial conversion. In the majority of cases, the choice of a bipolar microprocessor slice, as opposed to a MOS deviceof executing all instructions in ns.
Free Air Operating Temperature.
Permits multiplexing from N lines to 1 line. Specify by appending the suffix letter “X” to the ordering code.

The ‘ can be used as a 1- of demultiplexer by using one of the enable. The device should not be operated at these limits. 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 dztasheetimprove the quality and the reliability of its products. All inputs are protected from damagenoise Immunity, and low power consumption of CMOS with speeds similar to low power Schottky TTL circuitsInputs deter mine which one of the 16 normally high outputs will go 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.

Devices also available in Tape and Reel. Strobe enable line provided for cascading N lines to n lines. Operating Free Air Temperature Range. Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications. Two 74ls15 LOW enables G1 and G2 are provided to ease cascading of decoders with little or noappending the suffix letter datasheer to the ordering code.
The “Recommended Operating Conditions” table will define the conditions for actual device operation. Select inputs A and B are common to both sections.
Nevertheless, semiconductor devices in. All inputs are protected from damage due to static discharge byrouting applications.
