Differences between MSM82C55A-5 and MSM82C55A-2
1) Manufacturing Process
These devices use a 3 m Si-Gate CMOS process technology.
The MSM82C55A-2 is about 7% smaller in chip size than the MSM82C55A-5 as the MSM82C55A-
2 changed its output characteristics.
2) Function
The above function has been improved to remove bugs and other logics are not different between
the two devices.
3) Electrical Characteristics
3-1) DC Characteristics
As shown above, the DC characteristics of the MSM82C55A-2 satisfies the DC characteristics of the
MSM82C55A-5.
3-2) AC Characteristics
