General Description
Not remended for new designs. Please use HV632 instead. The HV622 is a 32-channel gray-shade column driver IC designed for driving electrofluorescent displays. Using Supertex’s unique HVCMOS® technology, it is capable of 256 levels of gray shading by PWM conversion. The shift clock is a balanced clock with electrical characteristics plying with EIA RS-422 standard. Input data, in groups of eight, is latched into a set of data latches on both edges of the shift clock. The data shifted in the first data latch corresponds to HVOUT1, the second data latch corresponds to HVOUT2, and so on. These data are pared to the contents of the master binary counter which...
