General Description
The HV9408 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.
These devices consist of a 32-bit shift register, 32 latches, and
control logic to enable outputs. HVOUT1 is connected to the first
stage of the shift register through the Output Enable logic. Data
is shifted through the shift register on the low to high transition of
the clock. The HV9408 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 (32). Operation of the shift
register is not affected by the LE (latch enable) or the OE (output
enable) inputs. Transfer of data from the shift register to the latch
occurs when the LE input is high. The data in the latch is retained
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 operatin
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.
