MSM82C51A-2RS/GS/JS
Differences between MSM82C51A and MSM82C51A-2
1) Manufacturing Process
These devices use a 3 m Si-Gate 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
Although the output voltage characteristics of these devices are identical, but the measurement
conditions of the MSM82C51A-2 are more restricted than the MSM82C51A.
3-2) AC Characteristics
As shown above, the MSM82C51A-2 satisfies the characteristics of the MSM82C51A.
