General Description
The HV93 and HV94 are low voltage serial to high voltage parallel
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, or large matrix LCD
displays.
These devices consist of a 32-bit shift register, 32 latches, and
control logic to enable outputs. HV
OUT
1 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 HV94 shifts in the counterclockwise direction when
viewed from the top of the package and the HV93 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 (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.

Notes:
1. Device will survive (but operation may not be specified or guaranteed) at
these extremes.
