The SN54AHCT14 and SN54AHCT14-SP datasheets also specify 112 pF.
The SN74AHCT14Q-Q1 and SN74AHCT14-EP datasheets specify 12 pF.
This looks like a typo.
Nick, the High Reliability group supports the EP device.
The SN74AHCT14 is per datasheet 2KV ESD and it is fabricated in a 1micron CMOS process.
I will let the logic team respond to ESD and process technologies for the other 2 devices as ESD is not listed…
