* : Although the I²C specification defines a condition that 300 ns of hold time is required internally, LC898214XC is
designed for a condition with typ. 20 ns of hold time. If I2CDT signal is unstable around falling point of I2CCK signal,
please implement an appropriate treatment on board, such as inserting a resistor.
