SN74LV273A: May I have some confirming item for SN74LV273A application ?

Part Number: SN74LV273A

Dear sir:

May I have some confirming item for  SN74LV273A application ?

If original our circuit use 74LVC273PW ,TI   SN74LV273A  part could replace it ? Or Any need consider or Risk ?

Change another word :74LVC273PW could use  TI   SN74LV273A  replace ?

(Change another word :TI   SN74LV273A could drop in compatible 74LVC273PW ?)


  • Hi Alex,

    This can be a drop in replacement. The only things you need to keep an eye on is that its minimum operating supply is 2 V rather than 1.65 V. However, with your application this isn't a concern since the supply is 3.3 V. The other thing to note is the SN74LV273A has a weaker drive. It looks like you are driving other CMOS device inputs so this shouldn't be a concern.
