(Note 1) Derate by 7.6mW/°C when operating above TA=25°C (when mounted in ROHM’s standard board).
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

(Note 2) Set “L” to CLB pin during power up. Set ”H” to CLB pin after power is stable.
When VDD become equal to or less than 2.2V, set “L” to CLB pin to clear the latch circuit.
(Note 3) The input signal transition should be linear. Noise shouldn’t be on these input pins as there is no hysteresis countermeasure on them.
The length of power and ground lines should be as short as possible and the bypass capacitor should be as close to the IC as possible so that
the ground noise caused by the current in its operation don’t cause any undesirable data errors.
The rise and fall times had better be smaller than the specified limits.
