74LS541 DATASHEET PDF
The SN54/ 74LS and SN54 / 74LS are octal buffers and line drivers with the same functions as the LS and LS, but with pinouts on the opposite. Texas Instruments 74LS Buffers & Line Drivers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Texas Instruments . 74LS datasheet, 74LS circuit, 74LS data sheet: ONSEMI – OCTAL BUFFER/LINE DRIVER WITH 3-STATE OUTPUTS,alldatasheet, datasheet.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
There are six of these on a single chip. Each has an output enable pin that can tri-state all the outputs. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
There are some other family offshoots; this list is those flavors of currently in production from one manufacturerTexas Instruments.
TI assumes no liability for applications assistance or customer product design. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. 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.
This method of combining multiple outputs on the same signal path is used heavily in microprocessor circuits, where several different memory or input circuits may be sharing a common set of data signals.
Esquema e software de gravador p via porta paralela – 74ls Alexandre row Enviado por: There are plenty of other useful chips in the 74LS00 logic family, but these are some of the most useful building blocks. The terminals are gold plated. Parts which are capable of having their output in any of these three states are considered to have “tri-state” outputs.
Tags Esquema e software de For a long time, the original series was the best choice as a general-purpose logic family, and the family had more members than any of the offshoot families.
74LS541 IC 8-BIT TRI-STATE DRIVER
Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. However, if you were picking a single “best” logic family today it would probably have to be the 74LS00 family. Products conform to specifications per the terms of Texas Instruments standard warranty. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. All input pulses have the following characteristics: The datassheet buffers 74LS and 74LS are functionally equivalent to the widely used 74LS and 74LS; however the ‘ and ‘ have a more confusing pin-out to trip the unwary student.
You might use these variants if you want to datasjeet in decimal digits rather than pure binary. There is a CLR input to reset the counter to This package can be hermetically sealed with a metal lid. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used.
The outputs are measured one at a time with one transition per measurement. Dattasheet has been announced but is not in production.
This drawing is subject to change without notice. However part of the current reduction in the 74LS00 family was on inputs, such that a typical 74LS00 family part can drive twenty LS loads that is, one output can fan out to twenty inputs within the 74LS00 family; compare this to the family, which could only drive ten inputs in the same family.
The 74LS is an eight-bit transparent latch, while the 74LS is an eight-bit edge-triggered latch. Two-input logic gates The five standard two-input logic gates in the 74LS00 family are listed in the table below. Production processing does not necessarily include testing of all parameters. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. TI has discontinued the production of the device.
This section introduces a number of useful digital logic chips for use in a variety of projects. The information provided on this page represents TI’s knowledge and belief as of the date that it is provided.

A tri-state datashedt or inverting buffer looks like a regular buffer or inverter, except there is an additional “enable” control signal entering the gate. Ordinarily this is a Bad Thing because outputs could drive into each other, but for open collector it’s fine: To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.
Device is in production to support existing customers, but TI does not recommend using this part in 74,s541 new design.
