Note The conditions of VINB = H is valid only at ch1, ch2 and ch6. The through current may be flowed, if the switching

operation is performed under the conditions of VINB = H at ch3 to ch5.

Remark The high impedance period of about 50 ns is prepared for the through-current prevention at the time of mode

switching. The tr (rise time) is designed as 50 ns, and the tf (fall time) is designed as about 50 ns.
