Other Parts Discussed in Thread: SN74LV221A , SN74LVC1G123 , SN74LV123A Hi,
I was wondering why there is a model of the SN74LVC1G123 / SN74LV123A but none of the SN74LV221A? I found this thread "e2e.ti.com/.../faq-why-is-there-no-pspice-model-for-a-monostable…

Part Number: SN74LV221A Other Parts Discussed in Thread: CD74HCT221 Hello
We have a product using the SN74HCT221A and evaluating whether the SN74LV221A will be a drop in replacement.
This thread describes a difference in the LV part:
SN74LV221A: SN74LV221A…
Part Number: SN74LV123A Other Parts Discussed in Thread: SN74LV221A Hi,
I have a question regarding the connection to GND of the pin CEXT of the monostable SN74LV123A.
In your SN74LV123A datasheet, the CEXT, apparently should NOT be connected to GND, or…
Hi Emrys,
Related to your last response:
SN74221NE4 is a PDIP 16 pin device Vs SN74LV221A SOIC.
The suggested part SN74LV221A but this calls for a design change(PWA), as I was actually looking for a drop in.
Also SN74LV221A parts seems have a different truth…
Hello,
It seems that you have certainly done your due diligence with testing this device. I'm afraid we won't be much help here. Although we continue to provide the legacy SN7400 series logic devices to anyone who wants to use them, we can only provide…

Thank you for your prompt reply. e2e has similar questions and different answers, so please check again.
The question is SN74LV123A、I think the following is a function block diagram of SN74AHC123. In this function block diagram, it is thought…
Hi Adam,
The SN74LVC1G123 is retriggerable only. If you'd like to use a non-retriggerable device, the SN74LV221A is a good option.
Large R and C values aren't a problem for most of our monostable multivibrators. The main concern will be the leakage…
Hi Paul,
The CD4000 technology family is best suited for 15V operation. In the case of a 3V supply I recommend using either the SN74LV221A or the SN74LV123A .
Thanks,
Anthony
