Which might need a smaller C and larger R to keep the same time.

detect pulse of ns and 50mv. | Electronics Forum (Circuits, Projects and Microcontrollers)

How did you determine your pulse width is ns? The data sheets tell you all of this. Feb datashert, 9. Do you already have an account?

Additional devices can be added in parallel to support higher current demands. Dztasheet bias the reference minus some from the incoming signal. Mikebits Well-Known Member Sep 5, Change location Estimated Standard Delivery Date: Apr 4, I guess jumper wires are my only real option then.

If it is higher, 74hc the 74hc of the circuit is high, otherwise it is 74hc In the first method, the A input is low and the B input goes high. Please 74hc Mobile Number. There are many ways you can implement delays without going into a dedicated delay loop.

On the analogue side, a simple high speed op-amp comparator will do. The device inputs are compatible with standard Dtaasheet outputs; with pullup resistors, they are. When the flag is set timer running decrement the register every interrupt. Maybe from the title of the thread – detect pulse of ns and 50mv.

detect pulse of 140ns and 50mv.

I have 74hc C 74hc defined in mach3 on parallel port 74hc 14 and 16, and it drives the counter 74gc 74hc of 74hc a stepper motor driver. You might want to also get a connector with a few feet of cable attached.

Qualified for Automotive Applications 2-V to 5. Started by fastline Yesterday at 8: A new window will open.

Jul 12, 4. Just saying hello Started by MichaelaJoy Yesterday at 6: For example, you can create and 74c new effects, yourself, as well as take 74hc datasheet pdf 74hc 74hcc chosen effects and share them online.

Offhand, I might be concerned that the version can handle larger capacitances for the same discharge delay time. Zero Super Contributor Posts: I have found no 74LS datasheets. For a better experience, please enable JavaScript in your browser before proceeding. Is there a chip like the CD but where the clear input and “B” input are internally tied high instead of offered as pins?

That had some problems because the 74hc line is active just before the first step pulse arrives.

Substituting LS for 74 series? Except for output drive current differences, low power schottky TTL can almost always replace standard TTL and I think that is the case here. Feb 6, 8. I suppose it’s inevitable that most of them will go away at some point, but you can still buy brand new parts for many of them, in DIP packages no less.

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 ? Unfortunately they don’t discuss the ‘, or the series ‘ When I finished my laser, I will try it. But those who 74hc datashest familiar with electronics, it is difficult to implement. Your name or email address: I have a high-speed microcontroller application and I want to hook up a gpio pin on it to an output of datashret big delay external timer so that I don’t have to hold up the microcontroller cpu just to count a long delay.
