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. Each time the master counter begins to decrement from 1111 1111, the data in the data latches are compared with the contents of the counter; if they match, the corresponding outputs will go high. The master counter counts down to 00000001 and then starts to count up again. The outputs that are at high will stay at high until the contents of the counter match the data in the data latches again.
