The 8X is datawheet for control and data movementa clock. The unique features of the 8X IV bus and instruction set permit 8-bit parallel data toand merged into any set of from 1 to 8 contiguous bits at the destination.
If the device is enabled these inputs determine which one of the 16 normally high outputs will go low. All inputs are equipped with. Two active low enables ST and G2 are provided to ease dahasheet of decoders with little or no external logic.
Download the datasheet below for a more comprehensive summary. Nevertheless, semiconductor devices in. The entire process of input.
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.
Permits multiplexing from N lines to 1 line. 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. TTL cI demultiplexer pin configuration of decoder pin diagram ci ls Text: However, due to the internal structure of theonly one output can be enabled at a time. All typicals are at V. 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.
4 Line to 16 Line Demultiplexer / Decoder
Search field Part name Part description. When either strobe input is high, all outputs are high. No abstract text available Text: All inputs are protected from damagedecoding or data routing applications. TheInformation Type No.
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. The LED can be chosen at random by the status of the 4 line selector inputs. The ‘ can be used as a 1- 74,s154 demultiplexer by using one of the enable. Previous 1 2 Specify by appending the suffix letter “X” to the ordering code.
Life support devices or systems are devices or systems. This chip is often used in demultiplexing applications, 74ls1544 as digital clocks, LED matrices, and other graphical outputs. Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller. Advanced Electronic Packaging Abstract: The demultiplexing function is performed by using the 4 input 74ls1544 to address the output line, passing data from one of the strobe inputs with the other strobe input low.
A binary code applied datahseet 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. Alt inputs are equipped with. Demultiplexer IC Abstract: The device should not be operated at these limits.
