  Hi Gil, Apologies for the late response. The IBIS model for https://www.ti.com/product/SN74AHCT245 should work fine for your device.

  Yes, the pictures are not SN74LVC8T245. I took a snap with wrong part(may be SN74LVCC3245A).. Compatible with SN74AHCT245 is meaning that only use 20 pins from the current PCB like below? Best Regards, Austin

  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,…

• RE: SN74LVC8T245: SN74LVC8T245PWR Overshoot and undershoot

  

  Clemens Ladisch

  Overshoots of this magnitude are likely to be measurement artifacts, usually caused by a long ground lead. Please show a photograph of your test setup. AHC devices have weaker output drivers. There is no exact replacement, but the SN74AHCT245 can put…

  Hey Jigar, Glad I could be of help. There are really two good methods of converting a unidirectional logic signal from 3.3V to 5V that I know of. The first is what Clemens recommended - and it's certainly an easy and good solution. You can use any TTL…

  user5355483

  I need to use the GPIO 145-gpio168 of TMS320F28377DZWT to drive IGBT, but the driving capacity of GPIO itself is too small and needs to be enhanced and expanded.The signal cannot be input into the PWM pin, and the TTL level can be directly converted to…

  Michael J Schultis

  Resolved

  Hello, Assuming you have a 5V supply connected to VCC, a 3.3V signal on the input is considered HIGH. This is a TTL compatible device, which means that the inputs interpret voltages greater than 2V as an input HIGH, and voltages less than 0.8V as an…
