Note 4: Since power supply pins 3 and 23 are connected in the IC, supply power to them at the same voltage.
If there is a large potential difference between the pins, a large current flows through the IC causing
degradation or damage due to heat stress.
Maximum ratings: A set of specified parameter values which must not be exceeded during operation, even for an
instant. If any of these limit values is exceeded during operation, it causes permanent damage to
the TC90A80N/F. Therefore, care must be exercised that the TC90A80N/F operates within the
specified ranges.
Recommended operating conditions: Minimum, typical and maximum values for key operating parameters such as
supply voltage, DC voltage and operating temperature. Ensuring that the
parameter values remain within these specified ranges during operation will
help to ensure that the integrity of the TC90A80N/F is not compromised. When
designing video equipment, be aware that the TC90A80N/F can function within
the recommended operating ranges.
