General Description
The HV66 is a low voltage serial to high voltage parallel converter
with push-pull outputs. This device has been designed for use as
a driver circuit for LCD displays. It can also be used in any appli-
cation requiring multiple output high voltage current sourcing and
sinking capabilities. The inputs are fully CMOS compatible.
The device consists of a 32-bit shift register, 32 latches, and con-
trol logic to perform blanking and polarity control of the outputs.
HVOUT1 is connected to the first stage of the shift register. Data is
shifted through the shift register on the logic rising transition of the
clock. A DIR pin causes data shifting clockwise when grounded
and counter clockwise when connected to VDD. 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 (blank) 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 after LE transitions from high to 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 GND.
Notes:
1. Device will survive (but operation may not be specified or guaranteed)
at these extremes
2. All voltages are referenced to GND
3. Duty cycle is limited by the total power dissipated in the package
4. For operation above 25°C ambient derate linearly to 85°C at 20mW/°C
