Manoj,
Looking over this schematic, I don't see any issues. The pull-ups are populated correctly on the input connections, the power supply pins are correctly decoupled, and the interfacing pins are correctly pulled up as well.
Please let us know if you have any other questions.
Regards,
Eric Hackett
