General Description
The HV55 and HV56 are low-voltage serial to high-voltage
parallel converters with open drain outputs. These devices have
been designed for use as drivers for AC-electroluminescent
displays. They 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.
These devices consist 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 HV55 shifts in the counterclockwise
direction when viewed from the top of the package, and the HV56
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. 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.
