hi , I want to use SN74ALVC245 for shifting the voltage from 3.3V to 1.8V. If my VCC is 1.8V will the inputs of the chip are tolerant to 3.3V? the datasheet VIH max value is not given and VI is given as 0 to VCC.
Thanks Prasanthi

Hi Prasanthi
Use one of these instead SN74LVC245A or SN74AUC245.
hi chris,
Thank you for reply.
sn74lvc245a is lvttl output. so I am not sure of it driving the 1.8V LVCMOS logic. can you suggest.
SN74AUC245 I can use but I want it to be future footprint compatible,
thanks
Prasanthi
