Part Number: SN74HC74 Other Parts Discussed in Thread: DSLVDS1047 , SN74LVC541A , DS91M125 Tool/software: We came across an instrument that has SN74HC74PWR, the two D flip-flips as divide by two counters cascaded, the first counter is driven by 4 MHz Pierce…
1. We need both the D and the CLK inputs, and an output. (It appears you have connected /Q to D, so we need only /Q and CLK.)
2. We need the abnormal waveform with the clock signals. You have shown only abnormal waveforms without the clock, and in those…
Part Number: SN74HC74 Hi
For this product, we made X-ray irradiation on the physical products with date code 2334 and 2308 and origin: Mexico and China respectively, and found that the internal structure was inconsistent.
Could you please help to confirm…
Part Number: SN74HC74 I've tried to find information on proper use of the TI part lookup and the result was 2,231 possible articles. I don't have time to wade through all that in hopes somewhere someone may have actually answered with something that…
Part Number: SN74HC74 Hello team,
My customer found the following behavior of SN74HC74.
Condition /PRE: H /CLR : H CLK : L
<Behavior> Despite retaining the above condition, the output of Q sometimes change from "L" to "H". This behavior…
Part Number: SN74HC74 Other Parts Discussed in Thread: SN74HCS08
Hi,
We have been using SN74HC74DR for a number of years without issue. Recently our production team started to notice failures in the test jig for one of our boards, caused by timing issues…
Part Number: SN74HC74 Other Parts Discussed in Thread: SN74LVC1G123 Hi team,
We are designing a circuit can generate 10ms low active signal to reset MCU, could you please if we can use SN74HC74 to realize this?
Appreciate if you can give us a reference…
Part Number: SN74HC74 As for SN74HC74NSR,I would like to know if barrier metal is used for the internal structure. I think it is configured to prevent the diffusion of metallic materials into the internal wiring and to prevent cross-reactions
Part Number: SN74HC74 Other Parts Discussed in Thread: TINA-TI About the simulation result of Tina9-TI
Timing simulation was performed on the attached signal generator circuit. If I change the time axis setting on terminal VF4, a different waveform will…
Part Number: SN74HC74-Q1 HI
I have encountered a problem with the application of the D flip-flop, the model used is SN74HC74-Q1. They are the schematic diagram and the waveform captured by the oscilloscope
CH1 (yellow) is the power-on waveform of the…
