Part Number: SN74AHC123A Hi team,
I'm trying to use the SN74AHC123ADR as a leading edge detector as the guide instructs, just like the following figure
However, I can only get the output pulse which has a min width of 53ns, while I look up the datasheet…
Part Number: SN74AHC123A Other Parts Discussed in Thread: CD74HCT123 , , CD74HC123 Hi, Teams,
Please help to double TI has the same as the 74HC123, and I have checked the TI family,
tw = K * RT * CT; need K=0.45 and tw<5ns.
CD74HCT123: K=0.45 but tw=17…
Part Number: SN74AHC123A Hi Team,
I want to check spec with you. I find there is no max value showing on datasheet. If our tw need to > 20ms which means that we don't need to connect Rext/Cext, is it correct? Thanks.
Regards,
Roy
Part Number: SN74AHC123A Is there a spice model for the SN74AHC123A? I have not been able to find one, but I would appreciate getting one to test out our circuits.
Part Number: SN74AHC123A Hi,
I am designed a timing circuit with SN74AHC123A
Requirements are Tw=22uS, VCC=3.3V
As per the calculation I have selected 1nF(1000pF) and 22.1K resistance.
But when I am observing , the output is around 50uS pulse width…
Part Number: SN74AHC123A Hi,
I have some SN74AHC123APWR that I am prototyping with, but I can't find a source from ti.com that shows what the pins are.
Have looked through most of the technical documents linked on product page.
Shouldn't this be in…
Part Number: SN74AHC123A
Hello,
I am trying to design a circuit that receives a pulse on the input, waits 2us, and then generates a pulse on the output.
I wanted to do this with the SN74AHC123A, but we need at least 5% tolerance on the pulse width. It…
Part Number: SN74AHC123A Hi all,
I want to make a one cycle pulse generator with an LM555 timer IC. The pulse timing after powering up the chip is: high (300ms) --> low (1s) --> high (continue until power off).
Help me make a circuit with the LM55…
Part Number: SN74AHC123A Other Parts Discussed in Thread: SN74LVC1G123 Hi,
Looking through the datasheet for the SN74AHC123A figure 9 shows the K value over capactiance and states that values of .001uF or greater equales a K value of 1 but the graph looks…
