In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. Sign up using Facebook. Full text of ” IC Datasheet: The outputs are active low, hence the outputs that are not addressed are high. After that I have taken a look at the datasheet of 1: Home Questions Tags Users Unanswered.

In the logic diagram of the 74LS, you have exactly that. If yes then how can I give it input and select lines?

Email Required, but never shown. Your explanation resolved my confusion. So, I was confused.

Post as a guest Name. Black Mamba 2. Search the history of over billion web pages on the Internet. Not more than one output should be shorted at a time, nor for more than 1 second. Here is the link to take a look at datasheet.

What, exactly, do you think the function of pins 1 and 15 are? The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs.
