Thread starter lofiboy Start date Dec 26, Prev 1 2. First Prev 2 of 2 Go to page. Hello Dear Friends, please I was given an assignment to design an 8-bit counter, 7-segment display with given components; TTL N, N family, power source, etc. We were actually instructed to design and simulate with Electronic Workbench Multism.
Please, I really need help. Thanks, Outlook Last edited: Dec 31, Roff Well-Known Member. Mr RB said:. I also have doubts about your first transfer chart for the B, where is it from?
Hook one up with a pot on the input and you should see a very obvious hysteresis right around the expected voltages. From my databook; BUB 1. Now the schmidt version; BUB 1. But maybe there are still some crap manufacturers that can't design a CMOS input pin circuit. Can you suggest a brand or chip I can test?? Because it was 2AM after a show and I could hardly see.
LOL Andy. Roman, you are wrong. With a 5V supply its switching threshold input voltage is anywhere from 1. Ordinary 74HCxxx high speed Cmos gates are the same. That is why an inverting gate can be used with a negative feedback resistor to make a linear amplifier. An inverting gate with a Schmitt trigger input cannot be a linear amplifier because the hysteresis will make its output latch.
Ron, I also agree with you and audio. I ran this test on 3 different gates. Vcc was 5. Results were as follows: 1. Vin was a triangle wave swinging between 1. Vout was a square wave at the same frequency. Roman, you are misinterpreting the input specs in the datasheets.
