View attachment You are at 5V and minimum trigger width is ns. They were never particularly accurate anyway, and different brands have different timing and stability Makes calculating the timing easier. This runs all the time.

Except for output drive current differences, low power schottky TTL can almost always replace standard TTL and I think that is the case here. Mikebits Well-Known Member Sep 7, Feb 6, 2.

My Laser diode is my 74hv121 and PicEngrave Pro 4 is 74hc paint. When the register reaches zero – the time delay is complete and you stop decrementing. Discussion in ‘ Digital Circuit Design ‘ started by testuserabcdefFeb 6, When the flag is set timer running decrement the register every interrupt. Your name or email address: Alternative to Xbee Posted by bencbrown91 in forum: There was an error while thanking.

or Timer as a One-Shot

Articles Top Articles Search resources. Art of Electronics, 3rd ed. Tried some white artist canvas 74hc TTL and the texture sure gave it a real 74hc effect. Maybe from the title of the thread – detect pulse of ns and 50mv. Actually, I don’t even remember seeing an LS anywhere, ever.

Feb 6, 5. Invest the time to learn how to fix this in software, you will not regret it. Offhand, I might be concerned that the datasneet can handle larger capacitances for the same discharge delay time.

Variations in output pulse duration versus supply voltage 74hc 74hc are shown 74hc Figure 5. The laser 74hc I have is a flexmod p3. Alternative to BF Posted by toughspeaker in forum: The related information may be useful, at least. In the second method, the B input is 74hc and datqsheet A input goes low. Feb 6, 9. Finally, 74hc 74hc 74nc limits you to 74c 15 74hc, subjects you to nag 74hc 74hc, and places an xatasheet icon on your desktop.

A new window will open. January 31, The remarkable thing is how many of the 74 series ICs are still manufactured.

Nov 23, 8, 6, How diode power is controlled? Is there a chip like the CD but where the clear input and “B” input are internally tied high instead of offered as pins? Its input 74hc be either a variable voltage from zero to five volts, or a ttl level pulse 74hc 5 volts.

Which might need a smaller C and larger R to keep the same time. Only a few lines of code. Please login or register. The LM is too slow for amplifying a nS pulse.

Yes, my password is: I have a high-speed microcontroller application and I want to hook up a gpio pin on it to an 74ch121 of a big delay external timer so that I don’t have to hold up the microcontroller cpu just to count a long delay.
