Hi,

I am using SN74AVC4T245 with both VCCA = VCCB=1.8V. DIR=OE=0

one my input 2B2 is at 3.3V standard toggling from 0 to 3.3V. will this create a problem?

will this 3.3V input converted to 1.8V on the other side that is 2A2 pin?

please help

thanks

Hey Prasanthi,

I would also like to add that you can switch to the SN74AXC4T245 device which is p2p and an upgrade to the SN74AVC4T245.

Hi,

This did not resolve my issue. by mistake it was marked as resolved.

please reply to the original question as the datasheet says the inputs are 4.6V tolerant.

also the link above says any input is tolerant up to 3.6V

Thanks

Prasanthi

No, this will not create a problem.
Yes, the 3.3 V input will be 1.8 V at the output.
