General Description
The HV623 is a 32-channel driver IC for gray shade display use.
It is designed to produce varying output voltages between 3 and
80 volts. This amplitude modulation at the output is facilitated by
an external ramp voltage V
R
. See Theory of Operation for detailed
explanation.
This device consists of a dual 16-bit shift registers, 32 data latches
and comparators, and control logic to preform 128 levels of gray
shading. There are 7 bits of data inputs. Data is shifted through the
shift registers at both edges of the clock, resulting a data transfer
rate of twice of the shift clock frequency. When the DIR pin is high,
CSI/CSO is the input/output for the chip select pulse. When DIR
is low, CSI/CSO is the output/input for the chip select pulse. The
DIR = HIGH also allows the HV623 to shift data in the counter-
clockwise direction when viewed from the top of the package.
When the DIR pin is low, data is shifted in the clockwise direction.
The output circuitry allows the energy which is stored in the output
capacitance to be returned to V
PP
through the body diode of the
output transistor.
