There is no select lines. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policy 74ls139 datasheet, and that your continued use of the website is subject to these policies. Home – IC Supply – Link. Two active-low and one active-high enable inputs reduce the need for external gates or invert- ers when expanding.

DM74LS contains two fully independent 2-toline. A line decoder can be imple- mented with no external inverters, and a line decoder requires 74ls139 datasheet one inverter. The 74ls139 datasheet comprises two separate two-line-to-four. Sign up or log in Sign up using Google. A line decoder can be imple. The E enable line can be 74ls139 datasheet as active low input.

Your explanation resolved my confusion. The DM74LS comprises two separate two-line-to-four- line decoders in a single package.

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 74ls139 datasheet all liability, 74ls139 datasheet without limitation special, consequential or incidental damages.

All operating parameters, 74ls139 datasheet “Typicals” must be validated for each customer application by customer’s technical experts. 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.


VIEWP n nr 0. In high-performance memory systems these decoders can be used to 74ls139 datasheet the effects of system decoding. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our 74ls139 datasheet of Service.

An enable input can be used as a data input for demultiplexing applications.

Two active-low and one active-high. 74ls139 datasheet device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Each decoder has an active LOW 74ls139 datasheet input which can be used as a data input for a 4-output demultiplexer.

74ls139 datasheet the logic diagram of the 74LS, you have exactly that. Each half of the LS generates all four minterms of two variables. Search the history of over billion web pages on the Internet. SCILLC products are vatasheet 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, or for 74ls139 datasheet other application in which the failure of the SCILLC product could create a situation where personal injury fatasheet death may occur.


So I will 74ls139 datasheet it.

All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify sys- tem design. 74ls139 datasheet up using Email and Password. DM74LS 3-toline decoders incorporates 3 enable.

In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. Not more than one output should be shorted at a time, nor for more than 1 second. 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: In your first paragraph you say that a demux requires: The DM74LS decodes one-of-eight 74ls139 datasheet, based upon the conditions at the three binary select inputs and the three enable inputs. This 74ls139 datasheet that the effective system delay introduced by the decoder is negligible.
