Product device recommended for new designs. Because tri-state buffers have many applications in microprocessor circuits, there are several useful chips available which are designed to function on eight data signals bits at one time.

Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual dztasheet of TI. The terminals are gold plated. Tri-state outputs allow multiple gates to “take turns” driving an output signal.


Important Information and Disclaimer: Samples may or may not be available. CL includes probe and jig capacitance.

Device is in production to support existing customers, but TI does not datazheet using this part in a new design. TI’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement datashet lead not exceed 0.

Body dimensions do not include mold flash or protrusion not to exceed 0, Each has an output enable pin that can tri-state all the outputs. The 74LS is identical to the 74LS except it only counts from 0 through 9 through binary ; the 74LS is similarly identical to the 74LS except for the limited range.


The package thermal impedance is calculated in accordance with JESD TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. These chips have convenient pin-outs separating the input side from the output side. This method of combining multiple outputs on the same signal datahseet is used heavily in microprocessor circuits, where several different memory or input circuits may be sharing a common set of data signals.

Please be aware that an important notice concerning availability, standard warranty, and 74ls5411 in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The 74LS00 family We’ve already spent time looking at the TTL logic family, even though I only introduced the first part in the family. You might signal a logic function to drive its output high or low as the function may determineand then later tell that function to turn off its output so that a different function may drive the signal instead.

The series was very successful and very popular, to the extent that when companies want to manufacture new logic parts with different electrical characteristics, they typically create new families of the very same functions and pin-outs.

If all outputs are off, the combination of signals is also off.

There is a CLR input to reset the counter to As long as other logic determines that no more than one output is driving the same signal at the same time, all is well. The 74LS00 family improves technically on the family in two key areas: In no event shall TI’s liability arising out of such information exceed the total purchase price of the TI part s at issue in this document sold by TI to Customer on an annual basis.

On all other products, production processing does not necessarily include testing of all parameters. Products datasheef to specifications per the terms of Texas Instruments standard warranty.

Two-input logic gates The five standard two-input logic gates in the 74LS00 family are listed in the table below. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.

The eight-bit buffers 74LS and 74LS are functionally equivalent to the widely used 74LS and 74LS; however the 74ld541 and ‘ have a more confusing pin-out to trip the unwary student.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. Not recommended for new designs. Along the way I’ll also cover some additional chip characteristics that can be useful in complex designs.

At the very least, they provide you with a lot of different options for creating complex logic functions and circuits.
