(*1) Although the I²C specification defines a condition that 300 ns of hold time is required internally,
LC898123F40XC is designed for a condition with typ. 40 ns of hold time. If SDA signal is unstable
around falling point of SCL signal, please implement an appropriate countermeasure on board, such
as inserting a resistor.
