Part Number: SN74LV123A Datasheet 10.2.1.1 Power-Down Considerations:
--
When a system containing this device is powered down, the capacitor can
Discharge from VCC through the protection diodes at pin 2 or pin 14. --
I think that the built-in protection…
Part Number: SN74LV123A Other Parts Discussed in Thread: SN74LVC1G123 Hello, My customer uses channel #1 but does not use channel #2 of SN74LV123A.
In this case, can 2Cext (pin #6) and 2Rext/Cext (pin#7) be left floating (unconnected to anywhere)? …
Part Number: SN74LV123A Could you please answer the "center value of thickness" and "tolerance of center value" of the DGV package of SN74LV123ADGVR? Customers are the first to mount the DGV package, and since this package has a narrow…
Part Number: SN74LV123A Hello,
I'm trying to simulate a falling edge detection using the SN74LV123A. The input signal (/A) is high @t0. Then it changes to low and remains low for 1us only. When the falling edge is detected the output (/Q) should change…
Part Number: SN74LV123A Hello,
We try to use SN74LV123ATPWRG4Q1 instead of SN74LV123APWR.
Because of delivery issue of SN74LV123APWR, but we found inventory of SN74LV123ATPWRG4Q1.
When look at the datasheet, there is no difference. What is difference…
Part Number: SN74LV123A Hi Team,
My customer is using SN74LV123A, only input B is used and the condition is L and ↑. /CLR pin is H.
Is it correct that input /A should be L to fulfill both L and ↑ for input B?
If so, customer will connect /A to…
Part Number: SN74LV123A Other Parts Discussed in Thread: SN74LVC1G123 , SN74LV221A SN74LV123A Differences in data sheet description
Hi, Staff
I was investigating the data sea about the terminal processing method when not using Rext/Cext, and there was…
Part Number: SN74LV123A Hello,
I want to use the IC as mono flop with 1us pulse width. According the formula in data sheet, page 15 and figure 12 this should be possible with Rt=1k and Ct=1nF.
See the pSpice simulation results below...>300us
What did…
Part Number: SN74LV123A Hi,
I have any questions.
1. Which of tMIR (= 0.3 x tw), tMIR (tPLH + tw) and trr is the minimum retrigger time?
2. The data sheet "10.2.1.3 Retriggering Data" states "the two adjacent input signals must be tMIR apart, where tMIR…
Part Number: SN74LV123A Hi,
How long is the maximum propagation delay when using 3.3V supply?
The values at 5V supply are described in P12, 9.3 Feature Description of the data sheet.
”The propagation delay has a maximum of 11 ns at 5-V supply.”…
