General Description
The HV5522 is a low-voltage serial to high-voltage parallel converter
with open drain outputs. This device has been designed for use as a
driver for AC-electroluminescent displays. It can also be used in any
application requiring multiple output high voltage current sinking
capabilities such as driving inkjet and electrostatic print heads,
plasma panels, vacuum fluorescent, or large matrix LCD displays.
This device consists of a 32-bit shift register, 32 latches, and control
logic to perform the polarity select and blanking of the outputs. Data
is shifted through the shift register on the high to low transition of the
clock. The HV5522 shifts in the counter clockwise direction when
viewed from the top of the package. A data output buffer is provided
for cascading devices. This output reflects the current status of
the last bit of the shift register. 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 register to the latch occurs
when the LE (latch enable) input is high. The data in the latch is
stored when LE is low.
