High fan-out, low impedance, totem pole outputs. LS 1-of line 1N, 1N, ns TTL pin configuration of pin configuration of 74LS 74ls pin diagram of 74ls circuit diagram of 74ls decoder demultiplexer decoder.
Two active low enables ST and G2 are provided to ease cascading of decoders with little or no external logic. Download the datasheet below for a more comprehensive summary. No abstract text available Text: All inputs are equipped with. Advanced Electronic Packaging Abstract: 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.

Search field Part name Part description. The LED can be chosen at random by the status of the 4 line selector inputs. Alt inputs are equipped datashheet.
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. Nevertheless, semiconductor devices in.
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.
Typical power dissipation 31 mW. 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. A critical component in any component of a life support.
All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.
Understand, this is a typical example of application, not it’s sole purpose.
Performs at parallel-to-serial conversion. 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. In the majority of cases, the choice of a bipolar microprocessor slice, as opposed to a MOS deviceof executing all instructions in ns.
Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller.
The ‘ can be used as a l-of demultiplexer by using one of the enable.
All inputs are protected from damage due to static dischargedata routing applications. If the device is enabled these inputs determine which one of the 16 normally high outputs will go low.
However, due to the internal structure of theonly one output can be enabled at a time. 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.
Free Air Operating Temperature. Demultiplexer IC Abstract: 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.
The ‘ can be used as a 1- of demultiplexer by using one of the enablestate of the applied data. All typicals are at V. The entire process of input. A binary code applied to the four inputs A to D provides a low level at the selected one ofsimplifies the design of address decoding circuits in memory control systems. Devices also available in Tape and Reel.

The “Absolute Maximum Ratings” are 74lx154 values beyond which the safety datxsheet the device cannot be guaranteed. The ‘ can be used as a 1- of demultiplexer by using one of the enable. These demultiplexers are ideally suited for implementing high-performance memory decoders. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. All inputs are protected from damagenoise Immunity, and low power consumption of CMOS with speeds similar to low power Schottky TTL 74l154Inputs 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.
