General Description
The HV53 and HV54 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 capa-
bilities 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. Q1 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 HV54 shifts in the counterclockwise direction
when viewed from the top of the package and the HV53 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.
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 maximum operating
temperature at 20mW/°C for plastic and at 15mW/°C for ceramic.
