General Description
The HV632 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.
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 counts on both edges of the count clock. Each...
