mA
Note: 1. In addition to not exceeding the total output current
ΣILED (from the absolute maximum ratings table), the segment output currents are allowed the
following values within a 700 mW total power dissipation range.
10’SHRag & d: Up to –78 mA
Others:
Up to –39 mA
Current flowing out of the IC is expressed with negative values, and current flowing into the IC is expressed with positive values.
2. The total variation in the oscillator frequency will be the sum of the precision and the stability. That is, the limiting values for the oscillator frequency
variation fall within the range from fosc - 19% to fosc + 21%.
