Hello, I am designing my device to use SN74LVC8T245. I am using B as input whit 3.3V supply and A as output using 3.3V supply also. According to datasheet at page 4:
Input voltage can be as high as 5.5V no matter my supply voltage in B which is the input is 3.3V ? Is that right or I am not understanding correctly ?
Active state is output ? Or Active State is input and 3-state is output not enabled ?
Yes, you are right. For you application, the input voltage can be as high as 5.5V no matter the supply voltage in B which is the input is 3.3V.
For the data in datasheet. the "active state" with Vcco max meas for output when in the enable state. The "3- state" column means the input range. The reason is this bi-directional buffer have two pathes, for example, when A-B is the transfer direction, the B-A path is in the 3-state. And can be provide 5.5V input at A side.
Any further thing, please let me know.
