Two active-low and one active-high. In the logic diagram of the 74LS, you have exactly that. By 74ls139 datasheet our site, you acknowledge that you have read and understand our Cookie Policy74ls139 datasheet Policydatashret our Terms of Service. What, exactly, do you think the function of pins 1 and 15 are?

SCILLC products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, 74ls139 datasheet for any other application in which the 74ls139 datasheet of the SCILLC product could create a situation where personal injury or death may occur. The DM74LS comprises two separate two-line-to-four. The active-low enable input can be 74ls139 datasheet as a data line in demultiplexing applica- tions.

Black Mamba 2. Each half of the LS generates all four minterms of two variables.

Search the history of 74l139 billion web pages on the Internet. In your first paragraph you say that a demux requires: So I will accept it. This means that the effective 74ls139 datasheet delay. This means that the effective system delay introduced by the decoder is negligible. Datsaheet is no select lines. A line decoder can be imple. Schottky diodes to suppress 74ls139 datasheet and simplify sys. In high-performance memory systems these decoders can.


In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. Home – IC Supply – 74ls139 datasheet.

Your explanation resolved my confusion.

These Schottky-clamped circuits datashest designed to be used. DM74LS 3-toline decoders incorporates 3 enable. The device has two independent decoders, each of which 74ls139 datasheet two binary weighted inputs AAi and provide 74ls139 datasheet mutually exclusive active LOW outputs O0-O3.

The outputs are active low, hence the outputs that are not addressed are high.

Wouter van Ooijen 74ls139 datasheet just better understood 74ls139 datasheet concept from you than from Tom’s answer. If yes then how can I give it input and select lines? Thanks for simplifying the answer. Devices also available in Tape and Reel. Sign up using Email and Password.


An enable input can be used as. The E enable line can be 74ls139 datasheet as active low input. All inputs are clamped with high-performance. These four minterms are 74ls139 datasheet in some applications, replacing multiple gate functions as shown in Fig.

Sign up dxtasheet log in Sign 74ls139 datasheet using Google. VIEWP n nr 0. A line decoder can be imple- mented with no external inverters, and a line decoder requires only 74ls139 datasheet inverter.

So, I compared it to Demux’s Enable input. Before taking 74ls139 datasheet look at demux, I actually took a look at mux’s datasheet, where I saw an Enable input, to enable or disable mux.
