  Part Number: SN74LV245AT Hi team, My customer is evaluating SN74LV245AT. In our datasheet, it mentioned below information. I think it should be the output current capacity for a single channel. If customer wants to use all the 8 channels, what's the…

  Part Number: SN74LV245AT Hi all Would you mind if we ask SN74LV245AT? In case of Isolation setting(/OE is high), will port A and B be High-Z? We could not find it on the datasheet. Kind regards, Hirotaka Matsumoto

  Resolved

  Part Number: SN74LV245AT Hi all Would you mind if we ask SN74LV245AT? When DIR is Low(B is input), /OE changes from Low to High. Do B ports stay input?(In this case, A ports are outport, however A ports are HighZ, so it is no problem.) Kind regards, Hirotaka Ma…

  When you go beyond the recommended operating conditions, the electrical characteristics are not longer guaranteed. For a 5 V supply, use a 5 V device like the SN74AHC245 or SN74LV245A. 3.3 V signals do not work with normal 5 V CMOS inputs. For those,…

  Hi Salah, What you're looking for is known as "flow-through architecture." There isn't an exact match for the SN74LV244AT, however most of our customers who want this feature use the SN74LV245AT and just fix the DIR pin permanently from…
