Differences between MSM82C37A-5 and MSM82C37B-5
1) Manufacturing Process
These devices use a 3 m Si-CMOS process technology and have the same chip size.
2) Function
These devices have the same logics except for changes in AC characteristics listed in (3-2).
3) Electrical Characteristics
3-1) DC Characteristics
These devices have the same DC characteristics.
3-2) AC Characteristics

68 ns minimum
As shown above, the MSM82C37A-5 cannot satisfy the clock low time of 68 ns (at automatic
initialization). On the other hand, the MSM82C37B-5 can satisfy the clock low time of 68 ns in any
operation status. As for the other characteristics, both the MSM82C37A-5 and the MSM82C37B-5 are
identical.
4) Package
The MSM82C37A-5 employed a PLCC package having OKI's original pin layout, which is not
compatible to AMD's PLCC products which has been commercialized before OKI's products.
To meet overseas customers needs, OKI has developed AMD-compatible PLCC
productsMSM82C37B-VJS. The OKI's DIP and FLAT package are identical to those of AMD.
