74LS139 – Dual 1-of-4 Dcdr Demultiplexer

Search the history of over billion web pages on the Internet. VIEWP n nr 0. Each half of the LS generates all four minterms of two variables. If yes then how can I give it input and select lines?

Your explanation resolved my confusion. So, I was confused. In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram.

In your first paragraph you say datasheeet a demux requires: The outputs are active low, hence the outputs that are not addressed are high. Full text of ” IC Datasheet: Thanks for the answer.

The E enable line can be used as datsaheet low input. Sign up using Facebook.

74LS – Dual 1-of-4 Dcdr Demultiplexer

SCILLC makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does SCILLC assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including 744ls139 limitation special, consequential or incidental damages.

Not more than one output should be shorted at a time, nor for more than 1 second. Each decoder has an active 7l4s139 Enable input which can be used as a data input for a 4-output demultiplexer.

These four minterms are useful in some applications, replacing multiple gate functions as shown in Fig. I just better understood the concept from you than from Tom’s answer.

In the logic diagram of the 74LS, you have exactly that.

There is no select lines.
