SN74LV4T08-Q1: Input Voltage Against VCC

Evan Wang

Part Number: SN74LV4T08-Q1
Other Parts Discussed in Thread: SN74LVC08A-Q1

Hi TI Expert,

I notice the SN74LV4T08-Q1 has the voltage Translation function but could we use it to replace below two parts directly?

1. SN74LV4T08QPWRQ1

2. SN74LVC08AQPWRQ1

I believe we can use the same voltage on both input and VCC.

So even we do not need any voltage translation function, we can still this it.

May I have your comment on above questions?

Thank you.

The SN74LVC08A-Q1 has different electrical characteristics (higher drive strength, I_off). But if you do not care about those, you can use the SN74LV4T08-Q1 instead.

Hi Ladisch,

My bad...

I meant to replace the SN74LV08ATPWRG4Q1 and SN74LVC08AQPWRQ1.

Seems like a yes to me if we want to replace them by SN74LV4T08-Q1 directly.

Is that correct?

Hi Chia,

Yes, you should be able to 1-1 replace.
