I find the Pin No. is wrong in Pin Function. Please double confirm it.

Hello Fei,
The pin functions table is incorrect - as you have shown.
The pinout drawing is correct - it has not changed in 40+ years.
I confirmed the bonding diagram and an old National Semiconductor databook. Not sure why there are two identical vertical pinouts shown...will also fix that.
Thank you for bringing this to our attention. I will put in a request for a datasheet update.
