74LS540 DATASHEET PDF

These devices are especially useful as output ports for the microprocessors, allowing ease of layout and greater PC board density. Motorola 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, or for any other application in which the failure of the Motorola product could create a situation where personal injury or death may occur. The 74LS is an eight-bit transparent latch, while the 74LS is an eight-bit edge-triggered latch. 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.

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

Should Buyer purchase or use Motorola products for any such. Latches The 74LS is an eight-bit transparent latch, while the 74LS is an eight-bit edge-triggered latch.

This section introduces a number of useful digital logic chips for use in a variety of projects.

Motorola products are not designed, intended, or authorized for use as components in. There are some other family offshoots; this list is those flavors of currently in production from one manufacturerTexas Instruments. These can be used in cases where the final output of a logic function only needs to sink current; a later section will give examples where this can be used.

The 74LS00 family improves technically on the family in two key areas: You might use these variants if you want to count in decimal digits rather than pure binary. Motorola 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, or for any other application in which the failure of the Motorola product could create a situation where personal injury or death may occur.

These chips have convenient pin-outs separating the input side from the output side. Min Typ Max Unit. Schematics and Components Previous: Although less common, there are decimal versions of these chips. There are plenty of other useful chips in the 74LS00 logic family, but these are some of the most useful building blocks. 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.

Open collector gates have an interesting property, which is that they can be ANDed together just by wiring several outputs together. These four-bit counter parts can count up or down. These devices are especially useful as output ports for the microprocessors, allowing ease of layout and greater PC board density.

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.

Motorola makes no warranty, representation or guarantee regarding. Two-input logic gates The five standard two-input logic gates in the 74LS00 family are listed in the table below. This family arguably has the widest manufacturer support and range of available line of components.

Motorola reserves the right to make changes without further notice to any products herein. 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 five standard two-input logic gates in the 74LS00 family are listed in the table below. These device types are designed to be used as memory address drivers.

Should Buyer purchase or use Motorola products for any such unintended or unauthorized application, Buyer shall indemnify and hold Motorola and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that Motorola was negligent regarding the design or manufacture of the part.

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.

If all outputs are off, the combination of ls is also off. 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 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 ls pin-outs. You might signal a logic function to 74ls50 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 only limitation of the 74LS00 family compared to the family is that the 74LS00 family can only source half as much current. 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.
