Part Number: SN74LV1T08

I am planning to use SN74LV1T08DBVR part for reset logic.

Can i connect the input A and input B at different voltage like input A is at 3.3V and input B is at 1.8 voltage ?

Hello Nitesh,

Yes, you can absolutely put different voltages into the inputs of the SN74LV1T08 - that's one of the great benefits of the LV1T family of parts!

You will just want to be careful to follow the V_IH and V_IL values shown in section 4.4 Electrical Characteristics on the datasheet. If your V_CC is larger than 4.5 V, then a 1.8 V input will not be recognized as a 'logic high'.
