Note: Limit value is beyond the scope of work, may damage the chip. Recommend the scope of work is

to point to in the scope, device function is normal, but does not guarantee completely satisfy the

individual performance index. Electrical parameter defines the components within the scope of work and

to ensure that the specific performance test under the condition of dc and ac parameter specification. For

not given the parameters of the upper and lower limit, the specification is not guarantee its accuracy, but

the typical value reasonably reflect the device performance.
