HVCMOS® technology
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.
5V CMOS inputs
Up to 80V output voltage
PWM gray shade conversion
Capable of 256 levels of gray shading
Balanced shift clock complies with RS-422
8MHz shift and count clock frequency
16MHz data throughput rate
8 bit data bus
The shift clock is a balanced clock with electrical characteristics
complying with EIA RS-422 standard. Input data, in groups of
eight, islatchedintoasetofdatalatchesonbothedgesoftheshift
clock. The data shifted in the first data latch corresponds to
HVOUT1,theseconddatalatchcorrespondstoHVOUT2,andsoon.
These data are compared to the contents of the master binary
counter which counts on both edges of the count clock. Each time
themastercounterbeginstodecrementfrom11111111, thedata
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.
