General Description
Not recommended for new designs. Please use HV632 instead.
The HV622 is a 32-channel gray-shade column driver IC de-
signed 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
complying 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
HV
OUT
1, the second data latch corresponds to HV
OUT
2, and so on.
These data are compared to the contents of the master binary
counter which counts on both edges of the count 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 0000 0001 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.
Therefore, the higher the binary data in the data latches, the
longer the outputs will stay at high. Thus, different high voltage
pulse widths are produced. When the counter reaches its
1111 1111 count while counting up, the device is ready for the
next operation cycle. A data value of 0000 0000 produces no
pulse; the output stays low.
The BLANK input signal will reset the master counter to all ones
(1111 1111) and set all high voltage outputs to low.
