The HV66 is a low voltage serial to high voltage parallel converter with push-pull outputs. This device has been designed for use as a driver circuit for LCD displays. It can also be used in any application requiring multiple output high voltage current sourcing and sinking capabilities. The inputs are fully CMOS compatible. The device consists of a 32-bit shift register, 32 latches, and control logic to perform blanking and polarity control of the outputs. HVOUT1 is connected to the first stage of the shi
