Other Parts Discussed in Thread: SN74LV123A Hello, I have a question about SN74LV123A.
The A-terminal is fixed to High.
Is it a problem that B-terminal is floating? Should I fix B-terminal to High or Low?
Regards, Dice-K
Hi,
I designed a circuit in Tina by using SN74LV123A monostable multivibrator. In this design I expect 110ms tw at the output pin(Q) of SN74LV123A . According to tw=K*R*C formula I used 11k resistor and 10u capacitor to obtain 110ms tw at the output…
Part Number: SN74LV123A Hello,
Regarding to the Tw(Output Pulse Duration Q/_Q) on SN74LV123A, my customer is asking following question.
･When temperature(Ta) is changed to Ta=-30C ->0C -> 25C,how is Tw changed?
(Supposing that the external capacitor…
Apologies for the delayed reply.
I have confirmed the SN74LV123A model consistently gives pulse durations longer than is specified In the data sheet.
Testing the pulse duration over six orders of magnitude shows that for longer pulse durations, the…
Part Number: SN74LV123A-Q1 I need a 229ms high output pulse when a low input edge is received.
Please check my selection for R , C for the used channel.
How do I terminate unused channel? Can I leave Cext, Rext/Cext pins open?

Other Parts Discussed in Thread: SN74AHC123A , SN74LV123A , SN74LVC1G123 Hi all, My customer would like to know the leakage current (Ii) characteristic data of Cext and Rext/Cet pins about SN74LV123A and SN74AHC123A as bellow;.
1. The data of leakage…
Other Parts Discussed in Thread: SN74LV123A I'm using the SN74LV123A PSpice model from TI site.
It works as expected when using small Cext of e.g. 150pF. The voltage on the capacitor drops from 4.983V to ~1V when triggered.
After changing the Cext…
Part Number: SN74LV123A-Q1 Hello,
I have some questions about VOH specification of SN74LV123A-Q1 (1) VOH at IOH=-50uA In the datasheet P.5, VOH(min) at IOH=-50uA is 0.1V. I think that the specification is typo. Could you please let me know the correct…
Other Parts Discussed in Thread: SN74LV123A Hi,
I would like to ask you about SN74LV123A irregular behavior as below.
0) Setting
- Rt=620K, Ct=0.1uF (60mSec), Tr=310K, Ct=0.1uF (30mSec)
- CLR pin is pull-up via 4.7K to 5V.
- "A" pin is pull…
Other Parts Discussed in Thread: SN74LV123A-Q1 , TINA-TI Hi
How to determine output load CL at the output terminal Q of sn74lv123a-q1?
CL=1000pF is not recommended?
Bestregards
