Notes:
1. All voltages are referenced to GND.
2. Duty cycle is limited by the total power dissipated in the package.
3. For operation above 25°C ambient derate linearly to maximum operating
temperature at 20mW/°C for plasitc and at 15mW/°C for ceramic.
General Description
The HV51 and HV52 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 and control logic to
perform the Output Enable and All-ON functions. Data is shifted
through the shift register on the high to low transition of the clock.
The HV51 shifts in the counterclockwise direction when viewed
from the top of the package and the HV52 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 OE
(Output Enable) or the STR (Strobe) inputs.
The HV51 and HV52 have been designed to be used in systems
which either switch off the high voltage supply before changing
the state of the high voltage outputs or which limit the current
through each output.
