They were never particularly accurate anyway, and different brands have different timing and stability Unfortunately they don’t discuss the ‘, or the series ‘ David Hess Super Contributor Posts: Except for output drive current differences, low power schottky TTL can almost always replace standard TTL and I think that is the case here. Dataasheet Super Contributor Posts: The remarkable thing is how many of the 74 series ICs are still manufactured.

Offhand, I might be concerned that the version can handle larger capacitances for the same discharge delay time. Are you sure the local one you have available is really LS?

Circuits Intégrés Logiques TTL

Actually, I don’t even remember seeing an LS anywhere, ever. The data sheets tell you all of this. Please login or register.

Most of the time this will work. Use flip-flops to build a divider.

If not, you could change some of the chips it is driving to LS also but then you need to check everything else downstream of those, etc Why not use the real deal? I just noticed that the National 74LS datasheet I found is mislabeled and is actually for the National so of course it is identical to the TI You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

Art of Electronics, 3rd ed. Which might need a smaller C and larger R to keep the same time. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

TI made a 74L which has about half of the drive capability but of course it draws about half of the power and is half of the maximum speed but otherwise looks like a direct replacement.

Drop me a message! It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.

Hero on January 31, Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

T3sl4co1l Super Contributor Posts: This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

I don’t recall all the specifics but LS is “Low power Schottky”, it seems to be the most common of all the 74xx series. I doubt there are many new products made that datasbeet them anymore. There was an error while thanking. The related information may be useful, at least.

It also analyzes transistor’s characteristics such as voltage and gain. In an existing antique circuit using one-shot, if the only repair part I can get locally is an ‘LS, any reason to not use this as a substitute for the ? Use dividers to build a counter. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

Datqsheet meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. The output waveforms can be both amplitude and frequency modulated.
