Yes I agree Emrys,
I just shared as reference and at times it might helps others too.
Meanwhile I have planned to have some tolerance captured in the test spec.
Really helpful discussion, thank you( Emrys & Albert ) for your patience in reviewing and…
Part Number: CD74HCT221 Hello E2E Experts,
Good day.
I am using the PIN 3 connected to Vcc without a pull-up and it works great. But then I asked myself if I had to use a pull-up but I wasn't able to find the information in the datasheet.
Do I have…
Part Number: CD74HCT221 Hi Support Team.
In the Qualification Summary, the results of ESD-HBM and CDM are described as "See data sheet". However, the datasheet does not show the results of ESD.
Please tell me ESD data (HBM data , CDM data) of…
Part Number: CD74HCT221 There is an error in the logic diagram. I know usage is on the decline and that Harris, or RCA before them, probably made the original error but I thought I would report it anyway. The A and B inputs are both driving the same line…
I did replace U1 IC with CD74HCT221, with same 10% Cap in place, 1% resistor in place.
Only change was the U1 IC part number, CD74HCT221 IC works as expected, output is very consistent with variation in the trigger frequency.
It will be really good to understand…
As shown in the switching characteristics table for t w , the tolerances are much larger than that.
(Why are you using an old TTL device? The CD74HCT221 would use much less power.)
Hi John and welcome to the forums!
I can't give details regarding internal projects, however I can say that we are definitely looking into the issue.
The LV221 is the only device that's shown this problem. I would recommend to instead use the HC…
