DATASHEET 74154 PDF

4-line to line Decoders/demultiplexers. Each or these 4-line-toline decoders utilizes TTL circuitry to decode four binary-coded inputs into one of. MOS technology. A binary code applied to the four inputs (A to D) provides a low level at the selected one of sixteen outputs excluding the other fifteen outputs. SNN .. of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration.

Datasheet PDF –

Y Decodes 4 binary-coded inputs into one of 16 mutually. As for the NAND gates, there is a function being implemented in which the gates are there to realize it. Download the datasheet below for a more comprehensive summary. Low Level Input Current. Office Distributors for availability and specifications. This allows more flexibility in the logic functions available. You can upvote more than one answer. Operating Free Air Temperature Range. Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller.

National Semiconductor

That is, if the outputs were active high, OR gates would perform the synthesis desired. National Semiconductor Electronic Components Datasheet. If Military Aerospace specified devices are required. Each or these 4-line-toline decoders utilizes TTL circuit.

Y Darasheet power dissipation mW. Absolute Maximum Ratings Note. Rather than providing only a single enable, both pins are used.

Note 3 I CC is measured with all outputs open and all inputs grounded. High to Low Level Output.

If you want to know exactly what is going on then draw out the truth table, but it is unlikely their function will make much sense to you. High Level Input Current. The person who took time to answer the question will appreciate that. Y Performs the demultiplexing function by distributing data. However, due to the internal structure of theonly one output can be enabled at a time.

Y Ratasheet Military Aerospace device is avail. High Level Input Voltage. These demultiplexers are ideally suited for implementing high-performance memory decoders.

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. Low Level Output Current. This chip is often used in demultiplexing applications, such as dztasheet clocks, LED matrices, and other graphical outputs. Home Questions Tags Users Unanswered. Understand, this is a typical example of application, not it’s sole purpose.

Email Required, but never shown. All the other ouputs stay high. Y Input clamping diodes datxsheet system design. When either strobe input is high, all outputs are high. WhatRoughBeast 49k 2 28 My first question is more important
