Can be used with the HV55 and HV56 to provide 300V
push pull operation
General Description
The HV45 and HV46 are low-voltage serial to high-voltage
parallel converters with P-Channel open drain outputs. These
devices have been designed for use as drivers for AC-electrolu-
minescent displays. They can also be used in any application
requiring multiple output high-voltage current source capabilities
such as driving inkjet and electrostatic print heads, plasma
panels, or vacuum fluorescent displays.
These devices consist of a 32-bit shift register, 32 data latches,
and control logic to perform polarity and blanking functions. Data
is shifted through the shift register on the logic high-to-low
transition of the clock. The HV45 shifts in the counterclockwise
direction when viewed from the top of the package and the HV46
shifts in the clockwise direction. A data output buffer is provided
for cascading devices. This output reflects the current status of
the last bit of the shift register. The data in the shift register is
latched when the latch enable pin is brought to logic high and then
returned to ground. If the latch enable pin is held high, the latch
becomes transparent and the shift register data is directly re-
flected in the outputs.
For applications requiring active pull down as well as pull up, the
HV45 and HV46 can be paired with the HV55 and HV56 devices,
respectively.
