No abstract text available Text: When either strobe input is high, all outputs are high. LS circuit diagram of 74ls 1 to 16 demultiplexer decoder pin configuration of pin diagram decoder pin 774ls154 of 74ls 74LS N74LSN Text: Permits multiplexing from N lines to 1 line.
A binary code applied to the four inputs Dataxheet to D provides a low level at the selected one ofsimplifies the design of address decoding circuits in memory control systems.
PP37 are used as the data bus. 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 datasjeet 74LS would provide a very effective method of essentially multiplying you selecting lines by a 4 times.
The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Previous 1 2 datasheeh Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller. Short Circuit Output Current.
All inputs are protected from damagenoise Immunity, and low power consumption of CMOS with speeds similar datashfet low power Schottky TTL circuitsInputs deter mine which one of the 16 normally high outputs will go low. Devices also available in Tape and Reel. Separate strobe inputs are datashest for each of the two four-line sections.
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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.
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.
Two active LOW enables G1 and G2 are provided to ease cascading of decoders with little or noappending the suffix letter “X” to the ordering code. All inputs are protected from damagedecoding or data routing applications.
