Hi ,

Octal Buffer IC SN74HC244PWG/SN74HC244PW is used in existing design. Since this part is obsolete, we identified the part SN74HC244APWR as alternate suggestion in TI website. Please confirm the difference between the SN74HC244PW and SN74HC244APWR and your suggestion for drop-in-replacement.

Also confirm the difference between the SN74HC244APWR and SN74HC244PWR.

Ignore the A suffix; there is no difference (see [FAQ] What is the difference between the SN74HCxx and the SN74HCxxA?). The SN74HC244PWR is cheaper.

The R suffix indicates a large reel; the chips are the same.
