General Description
The HV97 and HV98 are low-voltage serial to high-voltage paral-
lel converters with push-pull 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 sourcing and sinking capabilities such as
driving plasma panels, vacuum fluorescent displays, or large
matrix LCD displays. The inputs are fully CMOS compatible.
These devices consist of a 32-bit shift register, 32 latches, and
control logic to perform the polarity select and blanking of the
outputs. HV
through the polarity and blanking logic. Data is shifted through the
shift register on the logic low to high transition of the clock. The
HV97 shifts data in the clockwise direction when viewed from the
top of the package and the HV98 shifts in the counterclockwise
direction. A data output buffer is provided for cascading devices.
This output reflects the current status of the last bit of the shift
register (HV
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.
