About the switch time from the stand-by state to the state of operation When IN1, IN2, IN3, IN4 are "L", this IC has completely stopped operating. After the time of reset of about 7μs of an internal setting, it shifts to a prescribed output status corresponding to the state of the input when the signal enters the input terminal. Reset of about 7μs doesn't hang even if the motor is driven from the stand-by state when either CH drives and the output becomes an output status corresponding to the state of the input. As for full power TR between the reset time, turning off is maintained. 1ch input ON 2ch input ON Input OFF 2ch input ON IN1 OUT1 IN3 OUT3 Stand-by state There is no reset time when another CH drives.
