General Description
The HV9808 is a low voltage serial to high voltage parallel
converters with push-pull 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 sourcing and sinking capabilities such as driving plasma
panels, vacuum fluorescent, or large matrix LCD displays. The
inputs are fully CMOS compatible.
This device consists of a 32-bit shift register, 32 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 register on the logic low to high transition of the clock.
The HV9808 shifts data 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 (HVOUT32). Operation
of the shift register is not affected by the LE (latch enable), BL
(blanking), or the POL (polarity) in-puts. 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.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All
voltages are referenced to device ground.
Notes:
1. Duty cycle is limited by the total power dissipated in the package.
2. For operation above 25°C ambient derate linearly to maximum operating
temperature at 20mW/°C.

Power-Up Sequence
1. Connect ground
2. Apply VDD
3. Set all inputs (Data, CLK, Enable, etc.) to a known state
4. Apply VPP
Power-down sequence should be the reverse of the above.
The VPP should not drop below VDD during operations.
