When turning ON the power supply of the BU2050 serial IN/parallel OUT driver IC, can the initial conditions be set to all outputs 'L' or 'H' when turning ON the power supply?
The BU2050 has no power ON reset function, so the initial values of the internal shift register will be random. Setting /CLR='L' makes it possible for all CMOS outputs to be simultaneously at 'L' but not 'H'. But if the internal shift register is not set to that state beforehand initial random values will be output when /CLR='H'.
