There  are many  different  revisions of  datasheets  for this  2-chip
set. Those  listed above are the  only ones that could  be found. Each
source has a separate datasheet for each chip.

In the  first source, both  the actual datasheets  do not have  a date
associated with  them. the whole  PDF document is however  dated March
'93.  Therefore these shall be referred to as the Mar'93 datasheets.
 
In the second source, the dates for each datasheet are as follows: 
   82374EB EISA SYSTEM COMPONENT (ESC)   (Nov '93)
   82375EB PCI-EISA Bridge (PCEB)        (Oct '93)
Therefore these shall be referred to as the late'93 datasheets.

In the third source, the dates for each datasheet are as follows: 
   82374EB EISA SYSTEM COMPONENT (ESC)   (Nov '94)
   82375EB PCI-EISA Bridge (PCEB)        (Nov '94)
Therefore these shall be referred to as the Nov'94 datasheets.

The other datasheet's dates should be self explanatory, thus we have:
  1. Mar'93
  2. Late'93
  3. Nov'94
  4. Dec'95
  5. Mar'96
  6. Apr'97

The final, Apr'97 datasheet, is just a specification update.

The Late'93, and Nov'94 sources have an additional datasheet: 
82420/82430 PCIset BRIDGE COMPONENT, dated Oct'93 and Nov'94

These are the only sources of the Features>General: section.
