General Description
The HV579 is a low-voltage serial to high-voltage parallel con-
verter with push-pull outputs. This device has been designed for
use as a driver for electroluminescent displays. It can also be used
in any application requiring multiple output high-voltage current
sourcing and sinking capability such as driving plasma panels,
vacuum fluorescent displays, or large matrix LCD displays.
The device consists of a 64-bit shift register, 64 latches, and
control logic to perform the polarity select and blanking of the
outputs. HVout1 is connected to the first stage of the shift register
through the polarity and blanking logic. Data is shifted through the
shift registers on the logic low to high transition of the clock. The
DIR pin causes CCW shifting when connected to GND, and CW
shifting when connected to V
DD
. A data output buffer is provided
for cascading devices. This output reflects the current status of
the last bit of the shift register (HV
OUT
64). Operation of the shift
register is not affected by the LE (latch enable), BL (blanking), or
the POL (polarity) inputs. Transfer of data from the shift registers
to the latches occurs when the LE (latch enable) input is high. The
data in the latches is stored when LE is low.
