SN75DP139 circuit check

Dear Sirs,

I have a question.

Is there a problem part in the attached circuit connection?
Please let me know if there is a recommended value for VCC's bypass capacitor.
0.01 μF for noise removal was in the data sheet.

HI Yoshiki,

Schematic looks good, for pullups/pulldowns we recommend 4.7K to have stronger pulling and avoid 0ohms to avoid noise from GND or 3.3V

Bypass capacitor it is fine, this is how the EVM implements it.
